From co-creating regenerative cotton farms to creating custom pieces for all genders, our picks do more than just cover your ass. (though they do that too!)
This layer of clothing that is closest to your skin should be soft and comfortable. We’ve picked brands based on their use of natural and organic materials first and then their inclusivity and transparency about production. Some of these companies offer sleepwear or other clothing but our focus is on under garments in this guide.
Note: only one of these companies have highly constructed support bras. (and they are based in London) Most are more like bralettes and sports bras overall. Hopefully this will change in the future as more companies choose conscious manufacturing.
“The fashion industry is a dirty bastard. So we put sustainable thinking at the center of everything – that means we only choose fabrics that care for our environment and we only ever partner with factories that care about their impact, too.
When we say sustainability is our core mission we don’t mean that sustainability is nice to have – we mean that it’s the only way we act.”
Based in Denmark this Certified B-corp follows it through by continuously reducing their environmental footprint. These factories also ensure that their workplace is free of child labor and forced labor, their workers are surrounded in a safe working space, paid a living wage, offered employee perks like free lunch and childcare – and of course, they are treated with respect at all times. They’re also co-creating with WWF the first regenerative organic cotton farm in Turkey. Beyond that, they design for stuff to last.

Based in Australia, Boody prides themselves on sustainable fabrics which is why they use viscose derived from bamboo. The original bamboo is organic and grown without pesticides, fertilizers, or artificial irrigation.
