11 best sustainable and ethical underwear brands by fabric

Everyone needs and wears underwear, which means having sustainable underwear options are more important than ever. The fashion industry is one of the most polluting, and underwear is usually made from polyester which is essentially plastic, or super water-thirsty cotton. 

Seeing as underwear is always in close proximity to our most intimate areas, it stands to reason that we'd want the best quality and healthiest fabrics. 

Luckily, plenty of underwear brands have popped up to give us a solution to this problem. We've compiled an ultimate guide to sustainable underwear brands, grouped by the fabrics they all use, so you can be informed about what you're buying.
