Wearing organic cotton underwear is the best thing you can do for yourself and the planet, and here’s why!

Underwear is the first thing you put on, in the morning.

Underwear is the last thing you take off before you take a shower and go to bed.

And yet, not many people give underwear the respect it deserves.

In general, we are very careful as to what we expose our bodies to.

We count the calories in our food and analyze the ingredients in our skincare routine, aiming to lead a healthier lifestyle.

But skin does not stop with the face; there’s skin in our underwear as well – if you know what I mean.

Above all, organic cotton underwear is more comfortable and breathable than conventional ones.

Then, organic cotton basics are free of heavy metals, pesticides, and toxic dyes – critical to your health, as your undergarments rest around your private parts for at least 8-12 hours every day.

Now, most people I know do not wear organic cotton underwear (yet) because they don’t know which brands are sustainable, or where to buy them from.

Great news for you all, as I know the best sustainable underwear brands on the market right now, hence the reason for this article.

To help those of you looking for organic cotton underwear, I’ve put together this ultimate guide to sustainable underwear for both men and women.

In this guide, I’ll introduce you to the 25 best organic underwear brands right now, in 2021.

Each one of these ethical underwear brands is famous for creating some of the best eco-friendly basics, bras, lingerie, boxers, and briefs.

Also, these lingerie brands make their organic cotton underwear from certified organic cotton, obtained according to the Global Organic Textile Standard (GOTS).

Organic cotton is also a great choice if you fight against the climate crisis, pollution, and all waste caused by fast fashion.

So whenever you purchase a pair of ethically made organic underwear, you know it keeps you healthy and comfortable, while helping the environment in a big way.

Finally, I hope my article will help you be comfortable, confident, and sexy, all without compromising on your ethical values.

Without further ado, these are the best 25 organic cotton underwear brands in the world right now, in 2021.

1. Pact

Pact organic cotton underwear

Amazing organic cotton underwear for women and the ‘Give Back Box’ initiative which lets you donate old clothes to handpicked non-profit organizations.


$20 – $80


Growing cotton organically saves vast amounts of water and uses no toxic chemicals.

That’s one of the main reasons Pact makes their organic cotton underwear only from GOTS certified organic cotton.

For every item of organic cotton lingerie, the brand saves almost 4 gallons of water, compared to traditional cotton.

The brand also partners with ‘Fair Trade Certified’ factories across the world, aiming to provide safe working conditions and environmentally-friendly practices.

Fair Trade factories provide safe working conditions, empower and uplift local communities, and protect the environment.

Pact’s organic cotton underwear is very comfortable, has a soft touch, and above all, the brand has a timeless design.

Moreover, Pact is a certified B Corp that goes to great lengths to make sure its entire supply chain.

From the growing and harvesting of organic cotton to the final sewing and all the processes in between, everything is as responsible and sustainable as possible.

From all organic cotton underwear brands on this list, Pact is the go-to underwear and basics brand for my whole family!

2. Knickey

Knickey organic cotton underwear

A female-founded cotton underwear brand focused on creating high-quality sustainable, organic underwear.




I like Knickey a lot, as the founders care about putting people’s health first.

Taking note of the infections millions of women suffer from the synthetic fabrics and harmful toxins found in undies, Knickey uses only certified organic cotton.

Knickey’s fair-trade cotton underwear is breathable and free from chemicals and carcinogens.

Simply put, this is an underwear brand for undies free from anything unkind to your body, be that pesticides, toxins, or synthetic fabrics.

Also, the brand’s underwear is colored with Oeko-Tex certified, non-toxic dyes.

Knickey’s organic cotton underwear comes in a variety of styles to fit your preferences.

Also, you can buy starter sets to test out multiple fits before committing.

The brand stocks a wide range of XXS–XL range of thongs, hipsters, bikinis, and briefs (at low-, mid-and high-rise lengths).

Knickey will also happily take your garments back once they’re ready to be retired so they can be recycled safely and turned into new materials (like insulation).

Finally, when it’s time to replace your underwear, Knickey makes it easy with a recycling program that collects and recycles discarded underwear.

3. Organic Basics

Organic Basics organic cotton underwear

Organic Basics’ SilverTech undies for their antibacterial and heat-regulating properties.


$35 – $80


Organic Basics is a Danish brand that puts sustainable thinking at the center of everything

The brand is all about ethical and organic underwear (the clue is in the name), and only uses environment-friendly textiles.

The brand offers high-quality sustainable clothing for men and women, mostly in organic cotton.

Moreover, the brand has recently launched its first sustainable denim collection.

Most underwear by Organic Basics is made with GOTS certified organic cotton.

The brand uses only ethical factories and is very transparent about how and where every piece of underwear is made.

Organic Basics underwear and apparel are available in all sizes, from XS to XL.

Moreover, by weaving silver into the organic cotton, Organic Basics’ SilverTech pieces are antibacterial and heat regulating (it means your basics will need fewer washes than usually).

The brand even offers multi-packs of the most-loved sets and pieces, so that you can make the switch to a more sustainable underwear wardrobe with ease.

I’ve been wearing Organic Basics’ bras and undergarments for a few years now, and I can say each piece is amazing.

Even after several washes, my underwear and bras are still in excellent condition, soft and comfy as ever.

4. Brook There

Brook There organic cotton underwear

If you’re looking for organic cotton lingerie that goes back to the basics, this is the brand for you.


$25 – $70


Brook There makes some of the most elegant organic cotton sustainable lingerie pieces I’ve ever tried

The brand also blends natural ahimsa silk in its designs, with a focus on beautiful, long-lasting, soft, and comfortable fits.

Brook There lingerie and garments are designed, cut, and sewn on the coast of Maine.

Brook DeLorme and Daniel Pepice, couple and brand founders, insist on using organic cotton from the mills of North Carolina and California.

The brand has, initially, launched as a minimalist, organic women’s wear clothing line that blended confidence and comfort.

Since, the label has evolved to include lingerie, which became its central focus in 2013.

Brook There includes simple black and white bras and underwear, as well as more playful options, such as a ’50s-inspired gingham set with high-waisted bottoms.

The brand’s organic ethos reflects the couple’s lifestyle in Maine: DeLorme’s parents have an organic vegetable farm, and the couple buys and eats as sustainably as they can.

Fact: Brook designs every piece by herself, by starting with an idea, then a sketch, and a final draft before it shapes up as a pattern at her sewing machine, using measurements taken from real women.

Once the pattern is perfected, a small, dedicated team of sewers in Massachusetts craft the garments that eventually find their way to your doorstep.

When asked “Why organic? “, Brooke replied:

Part of the reason we choose organic is personal preference; it is healthier and it feels better against the skin. The other, and more urgent reason, is that organic cotton is better for the earth. Conventional cotton uses more pesticides than any other single major crop. By choosing organic, we preserve the health of our communities and ecosystems.

5. Pico

Pico organic cotton underwear

Pico produces essential, everyday goods, which can be traced right back to the source.

S – XL

Pico is a fully vegan British underwear brand known for its beautifully soft organic and fair-trade cotton underwear for both men and women.

That is super soft and simple, everyday underwear.

The create the morning underwear collection, the brand worked directly with a small fair trade factory in southern India, using organic cotton sourced from farmers’ cooperatives.

Project #2 – the founders have researched and learned about indigenous organic Indian cotton.

Now, they’re working with a cooperative in Gujarat to produce handwoven bath sheets and hand towels.

Nowadays, Pico is engaged in Project #3, learning about the British fiber industry and working with British manufacturers of cruelty-free wool.

Uye Surana organic cotton underwear

All pieces are handmade in a family-owned factory in Colombia, and then handprinted in a New York studio via a process that doesn’t use water or excess dyes.

So, if you’re eyeing something on their website, get it while you can before it’s too late!

Also, if you are looking for inclusive sizing, look no further.

With sizes ranging from XS to 3XL, Uye Surana is an inclusive lingerie brand that deserves your attention.

7. Nico

Nico organic cotton underwear

Apart from organic underwear, the brand also has products from eco-friendly regenerated cotton yarn that I highly recommend.

The brand brings high-quality basics and designer underwear to the Australian fashion landscape.

A range of organic cotton underwear that’s soft, supportive, and easy on the planet.


$35 – $195


Obsessed with color and detail, everything Araks makes is intended to let women feel at ease and beautiful.

In the founder’s vision, Araks organic underwear is meant to give women something that enhances, not distracts.

The brand offers underwear, sleepwear, swimwear, and resort wear.

I like Araks’s products as they don’t make a distinction between “everyday lingerie” and “occasion lingerie” when it comes to materials or craft.

To them, they’re all special.

In recognition of their efforts, Araks was selected to participate in the 2018-2019 CFDA + Lexus Fashion Initiative.

As of February 2020, all new pieces are made from organic cotton.

The fabric is GOTS certified, OEKOTEX 100 certified, and is made in Spain.

Ever since the company has made sure that all of their clothing is kind not only to the environment but also to your skin.

Every garment they do is free of toxic chemicals, and the undies are made with hypoallergenic organic cotton.

Every product is made to the highest ethical and environmental standards from start to finish.

10. Made Trade

Made Trade organic cotton underwear

Home to hundreds of sustainable brands for the entire family and home.


$15 – $45


Made Trade’s underwear list covers a few great brands and a large section of plus-size intimates.

At Made Trade you can shop freely, knowing each piece has been responsibly sourced, and expertly handcrafted with sustainable materials.

And, that the craftsmen and artisans are paid fair wages.

Every product on Made Trade adheres to one or more of the brand’s core values:

Fair Trade
– The brand’s underwears are handmade and adhere to international Fair Trade guidelines and labor practices.

– Handcrafted undies by artisans around the world using traditional art forms that are in danger of being lost forever.

– The brand’s products come from businesses or non-profits where 51% or more of the company is owned or run by a Black, Indigenous, or Person(s) of Color.

– Underwear made with earth-friendly materials, responsibly sourced, recycled, or upcycled, and intentionally designed to have a minimal negative environmental impact.

– Vegan products are 100% free of any and all animal products and byproducts.

– Underwear made by companies where 51% are identifying as women.

I recommend Made Trade for their wide range of organic cotton underwear, for all tastes and budgets.

11. Hanky Panky

Hanky Panky organic cotton underwear

Women-led with super comfortable organic cotton, all made in the USA

XS – 3XL

$20 – $100


If you’re looking for an underwear brand that makes all of its garments in the USA, Hanky Panky is the one for you.

Maybe some of you remember that 2004 front-page Wall Street Journal article describing Hanky Panky’s thongs as “lace butter”.

No surprise there are Hanky Panky garments are made from the best materials.

Components are chosen for their specific stretch qualities, softness, and fit.

Also, 100% of the fabrics and trims used to make our Signature Lace styles are knitted in the USA.

Even the Supima® cotton fibers used to make crotch linings are grown in the USA.

Moreover, this is a women-led company, and 100% employee-owned.

To top it up, the company runs a ‘Lingercycle’ program, where you can recycle your old underwear.

Highly recommended for their comfortable organic cotton thongs, hipsters, briefs, and so much more.

12. Warp + Weft

Warp + Weft organic cotton underwear

Excellent ultra-soft and ultra-stretchy underwear pieces, that retain shape even after several washes.

XS – 3XL



Family-owned Warp + Weft has been at the top of the organic denim business for over 30 years.

Thus, it should come as no surprise that the brand’s organic cotton underwear line is designed to be undetectable.

Free of sag and back side seams, these anti-pinch bikinis and briefs are lined in 100 percent organic cotton and made from cellulose reconstituted from beech trees.

Ever-inclusive, the collection includes sizes from 00–24, as well as various shades of nude.

The brand also recycles 98 percent of the water it uses, ultimately saving over 572.4 million gallons since launching in 2017.

With undies for every size and body shape, Warp + Weft’s products are naturally breathable and 50% more absorbent than cotton.

I like their ultra-soft and ultra-stretchy underwear line as it keeps shape even after several washes.

13. Nude Label

Nude Label organic cotton underwear

Great underwear made from organic cotton, grown with no pesticides, herbicides, or harmful chemicals.

XS – L

$15 – $60


Launched in 2014 by Clara Ropero and Ana Alemany with the aim of creating underwear that would feel like a second skin.

The designers, who met studying fashion design in Valencia, Spain, eventually moved home to launch their lines after both internings for brands in London.

Driven to create basic underwear that has the least environmental impact possible, the duo sources organic cotton locally, from Mataro, a town close to Barcelona.

Then, the underwear pieces are put together in a local factory in Valencia, owned by Alemany’s family.

Each piece feels soft and stunning, made from organic cotton certified with GOTS and OEKO-TEX 100 Standard – the brand is also a member of the Better Cotton initiative.

The designers use only friends and non-models in their lookbooks and campaigns because they want to save money for research and make sure their customers embrace self-acceptance.

I like Nude Label’s undies for their extra comfort – they do not use pads or underwires in their pieces.

Their underwear is refreshingly simple, with a neutral color palette, like a triangle mesh bra with a front cut-out.

14. Pansy

Pansy organic cotton underwear

Feel-good underwear: minimal, sturdy, beautiful, made entirely of organically grown natural fibers and sewn in California.

XS – 4XL

$35 – $65


Launched in the summer of 2012 by Laura Schoorl and Rachel Corry, Pansy is the perfect women’s underwear: minimal, sturdy, beautiful, and locally-made, this is feel-good underwear.

Pansy’s underwear is made entirely of organically grown natural fibers and sewn in California without a sweatshop in sight.

It is then dyed without the use of toxins and made with lots and lots of love.

I really like Pansy’s main collection of simple organic cotton underwear in low-rise and high-rise styles.

And, above all, I love Schoorl’s addition of a matching triangle bra in a variety of pastel hues, to the final line.

The designer says she is inspired by the nature and stays grounded by going to the countryside as often as possible.

And, you can see that in the brand’s latest organic loungewear; the styles, colors, and cuts all remind me of the countryside and village life.

15. Botanica Workshop

Botanica Workshop organic cotton underwear

Botanica Workshop’s delicate proportions, mimic serious lingerie but are designed for human movement.

S – L

$35 – $95


Botanica Workshop is an independent label focusing on underwear and loungewear made of organic cotton and sustainable materials.

Established in 2014, the brand was born from a need of producing natural intimates with a designer aesthetic and quality to match.

The name Botanica Workshop comes from a combination of concepts: “Botanica” which represents ecologically-minded use of materials, and “Workshop” representing the experiential nature of designing and producing handcrafted goods.

The label partners with local artisans and technicians to create small production runs of well-crafted pieces, a few times a year, in Los Angeles, CA.

Some of the brand’s high-profile customers include Natalie Portman, Marisa Tomei, Shailene Woodley, Kirsty Hume, Emma Roberts, Julie Delpy, Karen O., Brit Marling, Elise Crombez, and Linder Sterling.

16. Underprotection

Underprotection was founded in Copenhagen in 2010 with one important vision in mind; to unite sustainability and fashion.

The Danish brand is combining ethics and aesthetics in their pieces made from sustainable materials such as recycled polyester and organic cotton.

Underprotection exists to celebrate women of all kinds, and its goal is to make them feel as beautiful and comfortable as possible.

The brand is only using sustainable and certified materials such as organic cotton, TENCEL™ lyocell, recycled polyester, recycled nylon, recycled wool, and even banana fibers.

Most of their products are vegan approved, and if not, it is because it is either from recycled wool, or a rescued organic resource that would otherwise be wasted, such as milk.

All of its packaging, paper, and polybags are either recycled or biodegradable.

Moreover, the brand only works with certified factories as it believes:

fair working conditions and fair wages are human rights”.

17. Woron

Woron organic cotton underwear

No toxic chemicals, toxic dyes, no metal pokes, just basic underwear you’ll love to wear.


$25 – $50


Woron is a Scandinavian couture label specialized in high-quality, long-lasting vegan underwear.

The brand uses eco-friendly materials, such as Modal, and is Oeko-Tex certified, meaning there are no toxic chemicals or paints in their products.

The Copenhagen-based label is the result of a collaboration between two sisters – Arina and Anya Woron, passioned about sustainable underwear and everyday essentials.

The duo believes that most things in life can be fixed with a good attitude and some comfy organic underwear that does not compromise style and sexiness.

When the underpants aren’t riding up and the bra isn’t chafing or trying to suffocate you, when your body says “aaaah, I’m good right now”, that’s the magic of Woron“, said Anya Woron.

The brand has a wide range of organic cotton luxurious underwear made with a soft blend of plant-based goodness: natural breathable materials, chosen with women’s comfort in mind.

18. Skin

Skin organic cotton underwear

Big fan of the naturally hypoallergenic organic Pima cotton. When blended with lycra, the material is gently molding on my body, subtle shaping and enhancing my body’s natural curves.

XS – L

$25 – $100


Skin is a New York-based underwear label that creates perfectly cut tanks, pajamas, and lingerie, with flattering cuts and elegant styles for everyday use.

The brand has a wide collection of versatile, organic pieces that deliver in just about any situation.

Each piece is comfortable enough to wear under clothes and beautiful enough to wear as clothes.

I personally love them for their choice of clean and super-fine materials, which translates into modern silhouettes as celebrations of the environment and our bodies, in their most natural forms.

The unique construction of these garments, crafted without visible seams and finishings, eliminates any tightness or digging in, and around the garment’s ends.

Inspired by the feminine power and extraordinary natural beauty all women possess, Skin’s capsule collections are designed to uplift and honor the body through simplicity and naturalness.

This brand is a little more pricey than the others, but their organic cotton underwear is by far the best in the business.

19. Tomboyx

Tomboyx organic cotton underwear

Promoting sustainability as the common language of fashion, by encouraging everyone to be unapologetically themselves.

XS – 4XL

$20 – $40


Not only does this translate to gender and size-inclusive underwear up to 6X, but into ethical and eco-friendly products that customers love to wear.

Tomboyx uses Oeko-Tex 100 Certified organic cotton and provides fair wages to workers in women-owned facilities.

TomboyX was started in the founder’s garage, with the vision that everything they put on their bodies should make them feel great as they were, and help them express themselves without constraint.

From adaptive underwear to super-soft pajamas, the brand delivers high-end fit underwear of great feel, style, and colors.

20. Sustain by Kat

High-quality organic fabrics and natural dyes, all locally manufactured in Los Angeles according to the highest quality standards.


$35 – $75


Sustain by Kat is built on the three main tenets of Slow Fashion: making GOOD, CLEAN, and FAIR clothing.

Most of the label’s underwear is made with 100% organic cotton, while the trims are from natural rubber.

The label’s timeless basics last season to season, decreasing environmental impact while protecting your wallet.

Unlike conventional and other organic apparel, Sustain’s apparel is free of petroleum-based fabrics and dyes.

By using 100% natural materials, Sustain’s apparel is safe for your skin and the environment.

The brand has done so many amazing things when it comes to dyeing fabrics and making sure their garments are sustainable from the bottom up.

Every piece in Sustain’s collection is ethically made, from start to finish.

Sustain’s Ayurvedic collection supports small, marginalized communities in India by helping provide fair wages and safe working conditions.

Hailing from Hyderabad, the capital of southern India’s Telangana state, Mighty Good Basics aims to provide quality, affordable, organic, and fair trade underwear, for both men and women.

The brand uses GOTs certified cotton from the Rajlakshmi Cotton Mills in Kolkata, India.

The cotton is organically grown by farmers from the cooperative Chetna Organic, headquartered in Hyderabad India.

The brand also uses renewable energy throughout its supply chain.

Mighty Good Basics ‘Bare for Good’ campaign, now in its fourth year, was created in support of the #fashionrevolution movement to help promote a shift in the way we view fashion.

Azura Bay organic cotton underwear

Stocked with ethical brands that are using eco fabrics and ethical production processes as much as possible.

Also, when you make a purchase, the company donates a portion of the proceeds to a charitable organization of your choice.

I have purchased from Azura Bay many cute, comfy, and conscious lingerie pieces, even PJs, and loungewear.

Super comfortable organic underwear and if you want to buy multiple undies at once, the brand offers discounted multi-packs.

The brand uses its own unique textile, a mixture of organic cotton with hemp fabric.

    Hi Mandy,

    I loved your article. My twin brother and I are former Team USA athletes and we recently started Opok, a performance clothing brand that uses organic materials and is sustainably made. We launched our first product, boxer briefs about a few months ago and have had really great traction. What makes us unique is that we develop our products from Organic GOTS materials AND dyes to create a fashionable product that is built for active people in mind.

    We’d love to be considered for your article- let me know if you need any other information.

    My daughter asked me the other day, “mummy, why do we spend so much money on organic cotton underwear, is it really worth it?”

    I told her that organic underwear is better for human health and not only. Besides chemicals applied to crops before they’ve even been made into fabric, there are also all the chemicals added to non-organic fabrics before they’re sold to consumers. … Not only is organic underwear good for your health, but it’s also good for the environment.

    Teach them to protect themselves and the environment from an early age, that’s the only way forward!
