Few things are as personal as what we’re wearing under our everyday wardrobe. Our underwear starts our day with us; it should be comfortable, make us feel confident and effortlessly sexy, and—ideally—reflect our values for ethics and sustainability.
There are a growing number of ethical and sustainable clothing brands that respect both people and the planet. But ethical lingerie and sustainable underwear brands—especially ones that make us look and feel fantastic—are fewer and farther between.
If you’re ready to update your everyday essentials to underwear that is responsibly made, sustainable, and even organic, check out our favorite sustainable lingerie brands below. Then step up your next layer of comfies with our guides to sustainable athletic wear and pajamas.

And don’t even get us started on the high-rise brief—we wear it straight out of the clean laundry basket, it’s that comfy. Knickey will take old undies once they’re ready to be retired and recycle them into new materials like insulation, gifting you 15% off your order as a thank you!

The founders of Oddobody created their brand on the single enduring rule their mothers taught them growing up: that underwear should be cotton. The breathable, compostable fabric is ideal for healthy vulvas, so every pair is made from the highest quality, 100% GOTS certified organic cotton. With soft fabrics and comfortable fits (no riding!), Oddobody is one of our favorite underwear brands for lounging and sleeping. As a PBC, the brand is committed to opening up dialogues about our bodies, so each purchase comes with an artfully made body manual that offers body-related educational content (think: an intro to the pelvic floor, vulva care, and female sexual pleasure) through collaborations with experts. So cool!

We’ve tried Boody’s racerback sports bra and it’s the one we reach for from our drawer again and again. We recommend it for larger cup sizes for softness and support. In addition to Boody’s underwear, the brand also offers socks, activewear, and children’s clothing; shop bamboo basics for the whole family!
