Luxury begins with what’s closest to you...
String Nix is a modern British lingerie brand redefining the thong for the women who wear it and wear it well.
We believe underwear should never be an afterthought; it should fit flawlessly, feel effortless, and align with your values as much as your wardrobe.
Born out of a simple frustration that the perfect thong had vanished from the market, String Nix was created by Carol Wiltshire, a Creative Director with a background in media and a clear vision to bring back the barely-there, feel-good string thong, but elevated.
Our organic cotton thongs are designed to move with you. With carefully considered cuts, premium GOTS-certified cotton, and GRS recycled elastic, we’ve reimagined what a comfortable thong should feel like; soft, breathable, and made to last.
String Nix is a luxury lingerie brand that puts inclusive lingerie at its core. Our range includes six neutral shades of underwear for every skin tone, in sizes UK 8 to 18.
Whether you’re dressing for work, travel, or slow days at home, our sustainable underwear is designed to be the base layer that works with everything and feels like nothing.
From the fibres we source to the tones we offer, every detail reflects our commitment to comfort, longevity, and the quiet confidence of women who know themselves.
This is sustainable underwear that doesn’t chase trends, it sets a new standard.
