Black Friday 2026 at String Nix

I’ve been looking for organic cotton underwear that’s beige/skin colour, and been having a hard time so I simply found it through a lot of time on google. You have very poor competition in the UK because other options are often patterned/colourful so can’t be worn under some white/summer clothes. Also, most options I saw of nude/beige underwear are really large/thick designs so not very flattering. I appreciate that this is a little more feminine.

Honestly obsessed with these knickers! The material is incredibly soft, breathable, and feels amazing on the skin. They adjust perfectly to the body without digging in or shifting around. I especially love wearing them to the gym as they stay comfortable and in place no matter the workout. Definitely a staple!

Searched for so long to find organic cotton string underwear which wouldn’t show under gym clothes and these guys exceeded. The quality is unmatched. Won’t look back now :)

Superb quality, and great colours! Long lasting & wash amazingly! Definitely worth the purchase - my first ones are still going years & years later

I bought six pairs about a year ago and they have been so good. Really comfortable, soft, and they sit well under clothes without showing. A year on, they are still the pairs I reach for first. I have washed them loads and they have held up far better than I expected. Expensive, yes, but worth it. showing. A year on, they are still the pairs I reach for first.

These knickers are made from certified organic cotton and you can really feel the difference, super soft, breathable, and kind to my skin. The fit is amazing even after washing, I’d definitely recommend!! ❤️

I was so surprised by our comfortable these are! It’s been so tricky to find knickers that actually sit right and are comfortable - there are spot on. The sizing is well done, and the quality is amazing. All round a great product!

I’ve got two pairs in different colours - these are the best knickers I’ve got by a long shot. They’re so comfortable, the size fits perfectly and you can feel the fabric quality. I will definitely get more!

The Almond thong in an 8 is a great fit and true to size, really comfortable and lovely soft material . I’ve been looking for something like this for ages and I’m so glad I found it.

I’ve tried countless undies brands over the years, including some of the big names, and nothing comes close in terms of comfort, fit, and quality.

The organic cotton is lovely and soft without being flimsy, and the recycled elastic, (didn’t even know that was a thing) gives the right amount of support without cutting in.

I like that String Nix is built around everyday luxury essentials. It doesn’t feel like it’s trying too hard, it just is better.

No fast-fashion rubbish just beautifully made Nix and I’ve already recommended them to friends. I’ll be buying more, they are a game-changer.

I really like this product, they are extremely comfortable and don’t have any VPL at all. Can’t recommend enough, thank you.

Made with certified organic cotton which is super soft and extremely comfortable to wear.
They are easy to wash and I also put mine to dry in the tumble dryer on a gentle heat, even though it advises you not to tumble dryer them, they were fine, no shrinkage. Highly recommended.

I love my Nix, the quality is amazing and so comfortable.
