12 Plus-Size Brands Making Sustainable & Ethical Clothing Available To Every Woman

Fair Fashion For Every Woman

For sustainable fashion to transition from niche to normal, it’s vital that fair fashion be accessible to everyone who wants to engage in it—and that it include ethically made plus size clothing. For many women, the path to adopting the slow fashion movement is blocked as brands fail to offer inclusive sizes. 

Looking into the issue further, the problem often lies with the fact that so many sustainable brands are sole ventures or tiny, independent companies. But as the demand from conscious consumers has grown, so has the ethical fashion industry and its ability to offer broader and more inclusive product ranges. We were thrilled to find 12 sustainable brands offering ethically made plus size clothing for the curvy woman, from everyday basics to fabulous formalwear.

Thank you to our friend Sophie Benson for her collaborating research on this guide!
