Splendid Stripes That Actually Survive Childhood

Right, so we've created what might be the most gloriously striped children's t-shirt to ever emerge from a washing machine without falling apart. It's rather good, if we're being honest. The chunky stripes are utterly fetching, and because it's made from 100 percent GOTS certified organic cotton, your little one gets the softness of a cloud paired with the durability of, well, something considerably more robust than a cloud.

Why Choose Our Organic Multi Stripe T Shirt

Built to Withstand Adventures Organic cotton that's tough enough for climbing, exploring, and the occasional mud situation, yet soft enough that your child actually wants to wear it
Less Faffing About at Dressing Time Sizes 6 to 12 months and 1 to 2 years feature poppers on the neckline, because wrestling a toddler into a t-shirt is nobody's idea of fun
Environmentally Thoughtful AZO-free dyes mean you're choosing something better for your child and the planet, without any martyred sighs required
Beautifully Crafted Those signature chunky stripes aren't just for show—they're a proper showstopper that makes getting dressed feel like an occasion

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!

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.

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.
