A rather splendid ocean-inspired dress that's equal parts practical and utterly fetching. Our short sleeve summer dress features a gloriously full twirly skirt, perfect for those endless days of spinning about without a care. Made from 100 percent certified organic cotton, it's wonderfully soft against little skin and keeps children cool even when they're whirling around like tiny, enthusiastic dolphins.
Why Choose Our Sealife Summer Dress
Full Twirly Skirt: Designed for maximum movement and that marvellous swooshing sensation children adore, paired with fabric so soft you'll want to borrow it yourself (though we wouldn't recommend it).
Unique Design: A fabulously made Sealife print that celebrates the glorious creatures beneath the waves, because deep sea creatures deserve their moment in the sun.
100 Percent GOTS Certified Organic Cotton: Properly handsome fabric that's kind to skin and kinder still to the planet. No compromise, no fuss.
Environmentally Friendly AZO Free Dyes: We've taken rather good care to use dyes that won't fade your conscience or the dress itself.
Easy Care: Machine washable at 30 degrees, because we understand that life with children is beautifully chaotic and delightfully unpredictable.

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.
