11 Ethical Lingerie Brands For Sustainable Underwear
Sexy & Sustainable Underwear For Maximum Comfort
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. For a wider range of cup and hip sizes, check out our guide to size-inclusive lingerie brands!
