11 Best Comfortable and Sustainable Bras and Bralettes

Shopping for new bras can be hard. It’s hard to find the perfect size and style for you, and if you’re looking for a sustainable option, the selection gets even smaller.

To help you on your search for the perfect bra, we’ve sourced some of our favourite sustainable underwear brands, and sustainable clothing brands producing comfortable bras, from around the world. All of these brands use ethical and sustainable production processes, treating their workers ethically.

There are a few key things to look for when choosing a sustainable bra:

  • Materials: Sustainable materials often use less water, and are kinder on the planet.
  • Chemicals: Ideally, you should look for an OEKO-Tex Certified brand, which means they don’t use any toxic chemicals for their dyes.
  • Worker treatment: Look for brands that are transparent about their supply chain practices and factories.

The options here are all good choices. We’ve found brands from around the world, all offering unique styles and sustainable practices.
