Rather Good and Guilt Free
Look, we're not going to pretend that choosing an ethical swimsuit is exactly revolutionary. But here's the thing: this one actually works. The Petra gets you pool-ready without the nagging feeling you've rather let the planet down. Made from recycled bottles and printed with eco-friendly inks, it's the sort of thing that lets you swim carefree knowing you've given new life to materials that would otherwise have ended up, well, somewhere unfortunate.
Why Choose Our One Piece Swimsuit
Fabulous Fabric That Actually Lasts: 82 percent recycled polyester blended with spandex, chlorine-resistant and built to handle more than just the occasional splash. Made in Mexico City using slow fashion methods that don't rush the job.
Made to Order, Made Properly: Your swimsuit arrives within seven to twelve business days. Yes, you'll wait a touch longer than high street horrors, but that's rather the point. We make what you actually want instead of warehousing mountains of unwanted stock.
Designed for You, Not for Compromise: Cheeky fit, scoop neckline, low scoop back, and double-layer front for proper support. Zig-zag stitching means it stays put when you need it to.
Small, Independent, Woman-Owned: Your purchase supports genuine craftsmanship and sustainable practices, not shareholder meetings. Every order plants a tree.

SHIPPING + RETURNS
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!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES

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.
