Ethical Underwear Brands to Cozy up with this Winter

In these crazy times, I find myself, more than ever, relying on good basics. I mean this literally. The clothes that are in direct contact with my skin mean the most to me right now.

While we could all use some support, in more ways than one, some reliable physical support goes a long way toward making us feel better prepared to face the day.

If your underwear drawer could use a revamp, consider shopping ethical underwear brands to bring you a bit of feel-good, eco-friendly newness where you need it most.

Why Choose Sustainable Lingerie Brands?

What makes environmentally friendly underwear that different from a cotton value pack at Target?

First off, if we’re talking cotton, not all cotton fabric is made in the same way. Traditionally-made cotton fabrics undergo significant chemical processing, contributing to waste and pollution, and leaving traces of harmful toxins on your skin (which can cause yeast infections and possibly cancer).

Non-natural fibers like polyester and nylon are even more pollutive to produce, and shed tiny plastics into waterways each time they’re washed. They’re also not ideal for physical activity, since you’re essentially covering your privates in plastic, which – surprise – doesn’t breathe well. 

Natural fibers are the most skin-friendly, especially if they are grown organically and processed without toxic chemicals. On top of that, sustainable and fair trade underwear is made by people who are compensated fairly, in factories that minimize their waste and pollution, in a production cycle that minimizes environmental harm and actively seeks to lessen the fashion industry’s impact.

Top Ethical Underwear Brands

Thankfully, there’s quite a list of brands offering quality eco-friendly women’s underwear these days. To help you navigate the options, I’ll break down the offerings of 16 of my favorites, from affordable ethical underwear basics to reimagined lingerie.


Warp + Weft is known for their fantastic ethical jeans, but they also make a great pair of (seamless!) undies.
