The Rather Splendid Sweatshirt You'll Actually Want to Live In
Look, we're not ones to boast, but this longline sweatshirt is rather good. Exceptionally soft, beautifully made, and possessed of that marvellous quality of looking effortlessly put together whether you're pottering about at home or venturing into the world with something approaching confidence.
Why Choose Our Longline Sweatshirt
Genuinely Luxurious Fabric: We've blended 50 percent organic cotton with 50 percent modal because mixing nice things with nice things generally produces something quite the showstopper. The result is fabric that feels rather gorgeous against the skin and moves beautifully as you move.
Unisex Design: This isn't tailored to anyone in particular, which means it's tailored to everyone. Wear it oversized, wear it fitted, wear it however your heart desires without worrying whether you've picked the wrong cut.
Longline Length: The extended cut offers splendid coverage and a delightfully stylish silhouette that works brilliantly whether you're styling it with loungewear or your favourite everyday trousers.
Four Gorgeous Colours: We've offered enough choice to find something that speaks to you, but not so much that you'll stand there for twenty minutes unable to decide.

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

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.
