Bras can be a bit of a complicated topic to begin with… They can be so restricting and uncomfortable, it can be hard to find one that really fits you right, and there are all kinds of outdated and unnecessary social expectations that come along with bras, boobs, and nips.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).

The good news is that there are actually some great brands that now make non-toxic bras that are not only more sustainable but are also comfortable and high-quality. In this guide, you’ll find standard bras, bralettes, and sports bras that come in a wide range of styles and price ranges.

When it comes to 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!

What to Look for in a Healthier Bra

When shopping for bras and bralettes that are better for you and for the planet, here are a few things to look out for:

Natural, Organic, and Sustainable Fibers

Most of the bras that come from more ‘mainstream’ brands are made from synthetic fabrics and conventional cotton. 

Synthetics include things like polyester, nylon, and spandex. These types of fabrics have various pros and cons, but none of them are good for our ecosystem. Not only are they petroleum-based products, but they can also shed microplastics as they’re worn and washed, which are slowly starting to wreak havoc on plant, animal, and human life

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 the best choice because of the fact that it’s sprayed with lots of herbicides and pesticides and is quite water-intensive to grow.

Instead, look for organic and regenerative cotton when possible, which is 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.

In addition to organic cotton, we’ve also included hemp bras in this guide. Although this super sustainable fiber unfortunately got caught up in the war on drugs, 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 herbicides, pesticides, or very much water to grow, and it takes up less land than other comparable crops.

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,” “stain resistant,” and “water resistant.” This type of language usually indicates that a piece of clothing has been treated with toxic PFAS, a.k.a. “forever chemicals.”

Fair Labor & Ethical Manufacturing Processes

Considering the workers involved in your bra’s supply chain is an important part of 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?

Third-Party Certifications

Looking for third-party labels can be a helpful way to identify brands that are making better bras. These certifications 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 (which indicates the cotton has been grown using organic methods)
  • OEKO-TEX (which certifies that an end product has been tested to be free of a long list of harmful toxins)
  • Fairtrade International & Fair Trade USA (which verifies that the workers involved in the supply chain are paid living wages and work under safe conditions)

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.
