Finding a comfortable bra that we love, fits our body, and doesn’t dig into our skin can be challenging.

It makes shopping for sustainable, non-toxic bras extra difficult! 

In this article, I’ve rounded up the 9 best organic cotton bras & bralettes that combine comfort, support, softness, and sustainability.

Why buy organic cotton bras and bralettes?

The majority of conventional bras we typically find at the store or online are made from synthetic fabrics such as nylon, spandex, or polyester. 

There are many problems with that! 

We all know synthetics are unsustainable.

They’re derived from petroleum, an industry that is incredibly polluting and contributing to climate change.

They also shed thousands of microplastic particles in the wash and aren’t biodegradable. 

To top it off, these fabrics are often treated with harmful chemicals that can negatively impact our health in the long run. 

The breast area is one of the most delicate and sensitive parts of our bodies, and we do not want to put any harsh substances around there. 

For instance, many sports bras have been found to contain high levels of BPA, a known endocrine disruptor.  

Regular everyday bras aren’t any better!

An EPA-certified laboratory found detectable levels of organic fluorine in bras from major brands, which is an indicator of PFAS chemicals. 

PFAS can have a wide range of health effects, from reduced immunity and vaccine response to cardiovascular disease to endocrine disruption and increased cancer risk. 

Not to mention that synthetic bras aren’t breathable, which isn’t great for intimates. 

Now, you might be wondering: What is the healthiest fabric for bras?

Well, natural fabrics are your friends! 

We can often find bras made from conventional cotton, which are a lot better than synthetics as they’re breathable, moisture-wicking, soft, and comfortable to wear. 

However, conventional cotton contributes to a variety of environmental issues, so it’s not perfect.

Thankfully, we can easily avoid those by opting for organic cotton bras and bralettes! 

Organic cotton production promotes healthy soils, clean water, and thriving ecosystems, and positively impacts the farmers. 

Organic bras are also gentler on the skin and better for our health, and they tend to be more comfortable, softer, and of higher quality than most other fabrics. 

What to look for when shopping for organic cotton bras & bralettes? 

If you’re looking for sustainable, non-toxic bras made from organic cotton, see if you can buy pieces that are certified by GOTS or OCS to ensure the fabric is truly organic. 

Another certification I recommend is OEKO-TEX Standard 100.

This one guarantees that the product has been tested to be free of harmful chemicals, so it’s healthy to wear. 

I also like supporting brands that use non-toxic dyes, that make bras that are made to last, and that have implemented ethical and sustainable practices in their supply chain. 

For instance, some of the brands below reuse and upcycle their fabric scraps, work with Fair Trade-certified factories or offer carbon-neutral shipping. 

Of course, this goes without saying, but make sure to choose a bra that fits your body, feels comfortable and supportive, and that you love the style of.

No matter how sustainable or healthy a bra can be, if you feel bad wearing it, you just won’t touch it or will feel miserable wearing it.
