Rather Marvellous Vegan Silk Separates That Actually Work Together
Look, we've rather gone and created something rather good here. A unisex shirt and trousers set in 100 percent vegan silk that manages to be both splendidly relaxed and utterly fetching at once. Made from sustainably sourced wood fibres woven in Japan, these pieces have that gorgeous, lightweight feel against the skin that makes you forget you're wearing anything at all. Which is the whole point, really.
Why Choose Our Sky Set
100 Percent Vegan Silk, Properly Handsome. Crafted from cupro (vegan silk to those of us who prefer plain English), this fabric is breathable, anti-allergenic, and rather kind to sensitive skin. You'll wonder why you ever wore anything else.
Unisex Design That Actually Fits. Relaxed cut, natural Corozo buttons, and French seams throughout. Not a trace of that boxy nonsense. Delightfully stylish whether you're six feet tall or five foot nothing.
Sustainably Made in East London with Japanese Fabric. We source our materials responsibly, finish with care, and ensure every piece is fabulously made. No greenwashing, just honest craftsmanship.
Recycled Packaging Because the Details Matter. Your set arrives in packaging that's kind to the planet, which seems only fair given how kind this fabric is to you.

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
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us
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. Explore our British makers, discover sustainable brands, browse women-led businesses, find the perfect gift for her, or simply wander through our new arrivals and see what finds you.
This is just the beginning. But enough about us — read all about us, or step inside and see what catches your imagination.
A Curated Marketplace for Independent Ethical Brands
Discover our world of independent brands, conscious design, and purposeful creativity — all in one place.
Sostter is more than a marketplace. We're here to inspire a more thoughtful way to shop — one that celebrates the makers, the dreamers, and the independent brands doing things properly. Every brand on Sostter has been individually vetted for its originality, quality, and values. From sustainable fashion and ethical homeware to handmade jewellery and design-led gifts — all brought together in one considered space. Browse by location, by purpose, or simply wander and see what finds you. Want to sell with us? We'd love to hear from you.
