A Rather Splendid Seaside Adventure, Wrapped in Organic Cotton
Right then. We've gone and created something rather special here. This isn't just any children's t-shirt - it's the sort of thing that makes a genuine splash at the beach or, quite honestly, anywhere else you fancy wearing it. Featuring a beautifully soft applique sunset and seagull in vibrant orange, it's the kind of piece that arrives in the post and you think, well, that's rather marvellous, isn't it.
Why Choose Our Organic Seagull T Shirt
Utterly Fetching Design: A unique seagull and sunset applique that's been rather carefully crafted. Your child won't be seeing this at every turn, which is rather the point.
Softest Organic Cotton Imaginable: Spun from 100 percent GOTS certified organic cotton, this shirt feels as good as it looks. We're talking genuinely comfortable - the sort of fabric that doesn't drive you up the wall after an afternoon of wear.
Environmentally Friendly Through and Through: Made with AZO free dyes, because we rather believe children deserve better. No dodgy chemicals having a laugh on anyone's skin.
Neck Popper Fastenings on Smaller Sizes: A small but glorious touch that makes getting this on and off your little one rather less of a wrestling match. Proper genius, that.

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!

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.
