Bras can be a bit of a complicated topic, to begin with… Sometimes, they’re restricting and uncomfortable, so finding one that really fits you can be hard. 

And there are all kinds of outdated and unnecessary social expectations that come along with bras, boobs, and nips.

Add to that the fact that most bras are made out of synthetic fabrics that are not ideal to have against your skin (and are also not great for the planet).

There are actually some great brands that now make non-toxic and organic bras that are not only more sustainable but are also comfortable and high-quality. In this guide, you’ll find standard organic cotton bras, bralettes, and sports bras that come in various styles, sizes, and price ranges.

Regarding eco-friendly bras, there’s no reason to sacrifice comfort, confidence, and the right amount of support. We hope you can find your next favorite bra brand from the companies listed below!

These Are The Best Brands for Organic Cotton Bras, Hemp Bralettes, Non-Toxic Sports Bras, & More

Here are the brands to check out for the best organic bras. (If you want to learn more about what to actually look for in your healthy and sustainable bras, just scroll down!)

1. Subset (Best Overall)

  • Type: Bralettes
  • Price: $48
  • Sizes: XXS – XXXL
  • Made In: NYC

Formerly called Knickey, Subset’s everyday undies are designed to let your body and mind breathe easy, with super-soft certified organic cotton bralettes to benefit your body and the planet. Their mission is to make organic your daily default – and they’re definitely making this easy for us with their organic, size-inclusive bralette collection.

With colors good enough to eat, such as Butterscotch and Peachy Keen, and clear, transparent messaging about every product’s environmental impact, Subset’s toxic-free bralettes are a top choice.

They’re made in a fair trade factory, too.

My Take: I’ve been wearing Subset’s bras for several years now. My favorite is probably the Keyhole—it’s got adjustable straps, hook-and-eye closures in the back and has just the right amount of fabric where it feels very supportive, but still super comfortable enough for everyday wear.

2. Pact (Most Affordable)

  • Type: Bralettes, bra tops
  • Price: $25 – $114 (set of 3)
  • Sizes: XS-XXL
  • Made In: USA

Working with Fair trade factories to create their GOTS-certified organic cotton bralettes, Pact’s mission is to build Earth’s favorite clothing company. I think they’re on the right track – with soft triangle bras with adjustable straps, bra tops, and modern racerback bras all available in numerous colors, these bras ooze comfort.

As well as using organic cotton, Pact carbon offsets its shipping and thoughtfully chooses its packaging to minimize its environmental impact even further. Be sure to check out their full collection because they’ve got a lot of organic clothing for men and women.

My Take: I have several of Pact’s triangle bras, and I think they’re a great easy-to-wear everyday bra. They pull over, so you don’t have to worry about hooks, and they work with a wide variety of shirts.

3. Araks

Type: Bralettes, underwired bras
Price: $85 – $115
Sizes: XS-XL and XS D-Cup – LG D-Cup
Made In: New York, USA

Looking for lightweight bras and bralettes that come in enough colors to put the rainbow to shame? Araks is the one for you!

Araks’ consciously crafted cotton lingerie is composed of 70% organic cotton and 30% upcycled cotton mixed with wood pulp. Plus, they only work with suppliers who are as passionate about sustainable practices as they are.

Their organic cotton collection includes bralettes suitable for everyday comfort and underwired bras for when you need that extra bit of support.

4. MATE (Best for Organic Sports Bras)

Type: Sports bra, scoop bralette
Price: $42 – $58
Sizes: XS-3XL
Made In: USA

Most activewear isn’t great news for the environment – typically made from synthetic, plastic-based materials that release microplastics when washed. MATE’s Organic Stretch Sports Bra, however, is made from a blend of 92% organic cotton and only 8% spandex, so you can hit your low-medium intensity workouts knowing you’re wearing an earth-kind sports bra that’ll give you all the support you need.

Available in nine colors, this stretchy, unpadded, size-inclusive sports bra is constructed with double-layered fabric to provide enough coverage without suffocating.

They also have a Scoop Bralette that’s great for everyday wear. It’s a pullover bra made with 92% organic cotton and 8% spandex, with two layers for extra support.

It’s all colored with non-toxic dyes, and everything is made ethically in Los Angeles.

5. Thunderpants (Best for Fun Prints!)

  • Type: Bralettes
  • Price: $38 – $42
  • Sizes: S-2XL
  • Made In: Oregon, USA

We love Thunderpants’ unique, eye-catching wireless bralette prints – choose from designs such as Party Guac, Sketchy Snakes, or Marine Whales. They’re all designed by artists local to the minimal-waste factory in Oregon. They are made from certified Fairtrade organic cotton grown without any synthetic chemicals, pesticides, dyes, or other nasty stuff.

Pairing ultimate comfort with funky designs, these size-inclusive bralettes “might be the world’s most comfortable underwear.”

6. Sustain (Best for 100% Natural/Synthetic-Free)

  • Type: Bralettes & Sports Bras
  • Price: $56-70
  • Sizes: XS-XL
  • Made In: USA

Sustain checks all the boxes. They offer one of the very first 100% natural sports bras that have no synthetic materials at all. This makes it a great option for those with even the most sensitive skin.

These are made from organic fibers like 100% GOTS-certified organic cotton and a 100% organic wicking hemp lining (with an opening to insert soft cups or nursing pads). Even the elastic and thread used are made from natural and organic materials, making it suitable for the most delicate skin.

These bralettes and sports bras are available either in undyed or in a couple of beautiful shibori tie-dye colors—dyed from plants!

Everything is ethically designed and manufactured in Los Angeles.

7. Lé Buns (Australia-Based)

  • Type: Bralettes of various shapes
  • Price: $65
  • Sizes: 6-16
  • Made In: Australia

Each piece from Lé Buns’ collection is ethically made using sustainable materials like GOTS-certified organic cotton and non-toxic, eco-friendly dyes. Their team is committed to transparency, ethical manufacturing, and minimal waste throughout the entire supply chain.

Their bralettes and crop tops are available in various shapes, whether you’re looking for something for everyday wear, something more sporty, or even a strapless option. Made using 10% elastane, their pieces are just stretchy enough while still holding their shape as you wear them throughout the day.

My Take: I really love Lé Buns’ “Berta” bralette—I have that one in a few colors. It has more of a sports bra shape and feel, but feels more elevated than your standard sports bra. It’s probably one of the most comfortable bras I have. I wear it all the time, especially if I’m not feeling great or just really want to feel comfy but supported, too.

8. Object Apparel (Made in the USA)

  • Type: Bralettes
  • Price: $60 – $62
  • Sizes: XS-2XL
  • Made In: Detroit, USA

Object Apparel is committed to creating clothing that doesn’t harm the planet, using GOTS-certified organic textiles, natural plant dyes, and non-toxic water-based inks for all their stylish, original-artwork wireless bralettes.

If you think the original artwork is too nice to be hidden underneath a top, don’t worry – they’ve got ‘tank bralettes’ totally suitable for wearing on their own. Go show off the designs!

9. JulieMay (Best for Lingerie; UK-Based)

  • Type: Supportive underwired, non-wired, back support, sports bras, non-wired/bralette, front-fastening
  • Price: $61 (on sale) – $95
  • Sizes: 8-18, 32B-40G
  • Made In: UK

I love the selection Juliemay offers. These bras are made with organic cotton and silk, and they’re super comfortable and great for sensitive skin. Not only that, but they have a wide range of styles, shapes, and sizes (and they even offer custom sizing if you need it!). Plus, everything is ethically made in the UK using sustainable manufacturing practices.

If you’re looking for a bra that’s comfortable but still has a feminine design to it, you should definitely check out Juliemay’s collection.

My Take: I’ve been wearing JulieMay for a while now, and I have to say… They really did find the balance of comfy and sexy! Most of the fabric that’s actually against your skin is super soft—softer than cotton usually feels. (I say most because it depends on the style… As you can see pictured above, there’s a section of the panties that are just lace.)

The bras are lined with that same soft cotton, so even though it looks lacy, it feels more like you’re wearing that go-to, most comfortable set of underwear!

P. S. Make sure you use their sizing chart (with your exact measurements) before placing your purchase! They do offer the widest range of cup sizes of all of the brands on this list!

Use the code JULIEMAY for 10% off your first order.

10. WAMA

  • Type: Bralette
  • Price: $44
  • Sizes: XS-3XL
  • Made In: Vietnam

Another hemp industry pioneer, WAMA’s organic triangle or racerback bralettes are super soft, breathable, and will give you the support you need no matter your size. Choose from neutral tones or their signature ‘WAMA Green.’

They’ve got several environmental certifications, such as being PETA approved and a certified Green America business, and their dyeing facilities are Oeko-Tex certified.

As for sourcing their hemp from overseas, they’ve thought long and hard about where to source it from, and no other country can produce the quality of hemp fabric that China can. However, their undies are now made in Vietnam (in a WRAP certified facility), which has stricter standards than China when it comes to ethical labor.

Unhappy with your purchase? They’ve even got a first pair guarantee, where you can receive a new size, color, or a refund, no questions asked.

11. EmMeMa

  • Type: Bralette
  • Price: $40 – $73
  • Sizes: Custom fit
  • Made In: Canada

You’re spoiled for choice with EmMeMa’s range or organic cotton bralettes – whether you fancy a honey-bee patterned wireless, a red-chili colored padded balconette, or a reversible dog pattern, you’ll find it! There’s also an organic cotton nursing bralette available in ten different patterns.

They’re committed to having a minimal impact on the environment and to creating each piece in a healthy, happy environment. 5% of proceeds are donated to Wildlife Preservation Canada, which makes these bras a true planet-friendly choice.

As well as having sustainability as their core mission and being transparent about their impact, Organic Basics also has a ‘Body Friendly Manifesto’ where they’re publicly committed to expanding their size range and not using Photoshop on their models. This is the stuff the fashion industry desperately needs!

13. Eco Intimates

  • Type: Wireless bras and bralettes
  • Price: $24 – $67 AUD (on sale)
  • Sizes: A-G cup
  • Made In: Indonesia, Australia

Eco Intimates’ range of bras and bralettes aims to remain true to their ethos of creating natural lingerie to remind women how beautiful they are. Choose from pieces such as a pink floral bralette, a sheer silk black bralette, or a full-cup crop for extra coverage.

Using GOTS-certified organic cotton and produced in small batches by family-run makers in Indonesia, their lingerie is beautiful, ethically made, and kind to the planet and its people.

14. Afends

  • Type: Wireless bras, sports bras
  • Price: $35 – $65 (Set of 3)
  • Sizes: XS-XL
  • Made In: China

Afends’ bras are made with a combination of organic cotton, hemp, and elastane. Their wireless bralette (pictured above in white) is available in black or white and is a great everyday bra. It’s got adjustable straps and a hook-and-eye closure in the back.

Their sports bras (pictured above in green) are great not only for working out but also lounging around, running errands, or whatever else! Those are available in a lot of different solid colors, like purple, orange, and blue (in addition to the standard black and white).

  • Type: Bralettes, sports bras, compression tops
  • Price: $24 – $42 
  • Sizes: XS-4XL
  • Made In: Asia & South America

Tomboyx deserves an honorable mention here due to their inclusiveness and OEKO-TEX certified conventional cotton.

They’ve got the widest range of sizes we’ve seen, and where they can’t use cotton, they use TENCEL, which is synthetic fabrics’ more sustainable, less toxic competitor. Needing a rainbow-striped racerback bralette like, now? Head to Tomboyx.

What to Look for in a Healthier Bra

When shopping for bras and bralettes that are better for your skin, here are a few things to look out for:

1. Natural, Organic, and Sustainable Materials

Most bras from more ‘mainstream’ brands are made from synthetic fabrics such as polyester and nylon.

These fabrics have various pros and cons, but none are good for our ecosystem. They are petroleum-based products and can shed microplastics as they’re worn and washed, slowly starting to wreak havoc on plant, animal, and human life.

Plus, synthetics are more likely to contain toxic chemicals like heavy metals and endocrine disruptors. For example, in 2022, when the Center for Environmental Health tested polyester sports bras from several different brands, they found levels of BPA that exceeded the “allowable” amounts set by California Prop 65.

Then there are semi-synthetic fabrics, like rayon. Although these types of fabrics use plant material such as bamboo as their starting material, the manufacturing process required to transform those plants into a soft and silky fabric requires a few different toxic chemicals, which pose a big problem to the workers manufacturing them, along with the surrounding communities. Part of the problem is that not all rayon fabrics are created equal, and some are more toxic than others. You can read more about that here.

Conventional cotton is another fabric commonly used in regular bras, bralettes, and sports bras. Although it’s a natural fiber, conventional cotton is not always the best choice because of the fact that it’s sprayed with lots of pesticides and is quite water-intensive to grow. That being said, even conventional cotton tends to be better than polyester for those with sensitive skin.

But your best bet is to look for regenerative and organic cotton when possible. It’s grown using methods that are not only healthier for the soil, but also better for the pollinators, the farm workers, the surrounding communities, and our overall ecosystem.

Plus, some organic certifications like GOTS also have rules about what can be added to the fabrics—think dyes, “performance” finishes, etc. So organic bras are much less likely to have toxic chemical additives.

In addition to organic cotton, I’ve also included hemp bras in this guide. Although this super sustainable fiber unfortunately got caught up in the war on drugs and has therefore not been widely used in consumer goods, we are beginning to see an increase in hemp underwear, clothing, and other hemp products on the market.

Hemp is a really awesome eco-friendly fabric: it’s breathable and naturally anti-microbial, it’s soft and strong, and it has several sustainable qualities to it. It’s not picky when it comes to climate (it will grow in a variety of different regions), it doesn’t require pesticides or very much water to grow, and it takes up less land than other comparable crops.

2. Non-Toxic Dyes & No Added Fabric Treatments

The other thing to consider when shopping for bras is how the fabric is dyed and treated. Look for azo-free dyes (or even better: dye-free) whenever possible.

Additionally, try to avoid words like “moisture-wicking,” “anti-wrinkle,” and “stain-resistant.” This type of language usually indicates that a piece of clothing has been treated with toxic PFAS, formaldehyde, or other toxic chemicals.

You can read more about toxic additives in clothing here.

3. Fair Labor & Ethical Manufacturing Processes

Considering the workers in your bra’s supply chain is important in evaluating safety and sustainability. Look for brands that are committed to transparency when it comes to the factories they work with. Where are the factories located? Do they own the factories and/or visit them regularly? How can they guarantee that workers are safe and paid a living wage?

4. Third-Party Certifications

Looking for third-party labels can be a helpful way to identify brands that are making better bras. These certifications are not perfect, but they indicate that a brand or product has been tested and verified using a third-party set of criteria.

Some of the labels commonly used for non-toxic and eco-friendly bras include:

  • GOTS organic: This indicates the cotton has been grown using organic methods.
  • OEKO-TEX: This label certifies that an end product has been tested to be free of a list of harmful toxins.
  • Fairtrade International & Fair Trade USA: Bras made in a fair trade factory means the workers involved in the supply chain are paid living wages and work under safe conditions, and that no child labor is used.

5. A Bra That Makes You Feel Good!

Lastly, make sure your bras fit well and feel good! Don’t like underwires? Don’t buy them! Prefer sports bras or bralettes over traditional bras with padding? Go for it. You deserve to wear clothing that is not only non-toxic and sustainable but also leaves you feeling comfortable and confident.

Everyone deserves to wear undergarments that are not only non-toxic and sustainable but are also comfortable and help us feel good as we move throughout our days.

This guide brought you some of the best eco-friendly and organic cotton bras, bralettes, and sports bras to try the next time you go bra shopping.

  2. So many options but after looking at most of the products, they all have spandex, elastane, or some similar stretch material. I’m super allergic. If you ever find any truly all cotton bras or bralettes, I’d love to know about them.
