Stargazing Never Looked So Rather Good
Look, we'll be honest. This bikini is doing rather a lot of heavy lifting. It's a string bikini that actually feels fabulous to wear, it's made from ocean-recovered recycled bottles, and it looks utterly fetching in this glorious Blue Copernicus shade. Frankly, we're a bit gobsmacked by it ourselves.
Why Choose Our String Bikini
Made From Rescued Ocean Plastic: Those 88 percent recycled polyester fibres used to be plastic bottles drifting about feeling sorry for themselves. Now they're doing rather splendid work keeping you comfortable and stylish.
Sun Protection Built In: UPF 50 plus protection means you can swim and sunbathe with the sort of carefree confidence that comes from proper sun safety.
Non-Toxic Inks: We've used eco-friendly inks because what's the point of wearing recycled fabric if we're going to spoil it with dodgy chemicals.
Beautifully Crafted in Mexico City: Each piece is made to order by skilled hands who actually care about what they're making. Proper craftsmanship, that is.
Supporting Independent Creation: Every purchase goes toward a female-owned business committed to slow fashion and genuine sustainability. Your hard-earned money goes somewhere that matters.

THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!

We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
