Rather Good Looking, Remarkably Sustainable
The Cygnus Swimsuit is that rather splendid thing you find and wonder how you ever lived without it. Cut from recycled ocean plastic transformed into silky recycled polyester, it fits like a glove and somehow makes you feel like the best version of yourself. Pair it with round sunglasses and Nancy Sinatra on the speakers, and well, you've got yourself a proper moment.
Why Choose Our Swimsuit
Ocean Rescued Materials: Made from 88% recycled polyester derived from reclaimed plastic bottles, this isn't virtue signalling, it's the real thing. You're literally wearing rescued ocean plastic that looks marvellous.
Sun Protection Built In: UPF 50+ protection means you can swim, splash, and lounge without the worry. Rather clever engineering, if we're honest.
Snug, Supportive Fit: The fabric hugs like a glove with a touch of elastane for genuine comfort. We suggest sizing up one size for that utterly fetching, relaxed fit. The model is wearing size Small, naturally.
Made to Order Means Better for Everyone: We create each piece specifically for you, which means less waste, fresher arrival, and the knowledge that your purchase supports slow, thoughtful fashion. Seven to twelve business days might feel like an eternity, but it's worth the wait.
Thoughtfully Crafted: Non-toxic inks, certified sustainable practices, and production in Mexico by artisans who genuinely care. Every order plants a tree. That's the sort of thing that should make you feel rather good about what you're wearing.

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.
