The Rather Splendid Sweatshirt You'll Actually Want to Live In

Look, we've all tried on sweatshirts that promise comfort and deliver something closer to a wool blanket with sleeves. This one is different. Crafted from a rather fabulous blend of organic cotton and modal, it's soft enough to make you question why you ever wore anything else, yet substantial enough to look intentional whether you're pottering about at home or venturing out into the world.

Why Choose Our Boxy Sweatshirt

Gloriously Soft Construction The combination of 50 percent organic cotton and 50 percent modal creates something utterly fetching. It breathes beautifully, moves with you, and honestly feels rather good against the skin.

Unisex Cut That Actually Works No awkward sizing compromises here. The boxy silhouette is designed to be genuinely comfortable for everyone, draped in all the right ways without trying too hard.

Versatile Colour Palette Available in four carefully chosen shades, so you can actually find one that suits your life rather than the other way around.

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!

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.
