Why Organic Cotton

Organic cotton is soft, breathable, and gentle against the skin. String Nix is made using GOTS Certified organic cotton, chosen for comfort and quality. It is a considered alternative to synthetic underwear that can feel restrictive or irritating.

The benefits

Designed For No VPL

String Nix is designed to sit smoothly against the body without digging in or showing through. The slim string thong shape gives a clean finish under trousers, dresses, tailoring, gym wear, and everyday outfits.

Fit & Sizing

Available in UK sizes 8 to 18, String Nix is designed for a comfortable, secure fit that stays in place throughout the day. The feel is soft, light, and barely there, without losing the confidence of a proper fit.

Skin Tone Inspired Shades

Our range includes Almond, Caramel, Cinnamon, and Chocolate, alongside classic Black and White. Almond is the strongest choice under white trousers and lighter fabrics, while the full shade range gives more women a better everyday option.
