Where Sustainability Meets Everyday Luxury...

String Nix is a British luxury lingerie brand transforming the everyday string thong into an icon of comfort, elegance, and sustainability. Founded by Carol Wiltshire, the brand was born from a frustration familiar to women everywhere: the lack of high-quality, long-lasting underwear that fits beautifully.


Every piece is crafted from GOTS-certified organic cotton with recycled elastic waistband, combining ethical production with an exceptional feel. The collection spans six inclusive shades Black, White, Almond, Caramel, Cinnamon, and Chocolate and sizes UK 8–18, ensuring every woman can find her perfect fit. Thoughtful touches extend to FSC-certified packaging, recycled labels, and garment liners, reflecting a holistic commitment to sustainability.
