Soft, Sustainable Comfort for Your Little One
Right, let's be honest. Babies are rather marvellous at creating chaos, but they deserve clothing that's equally fabulous. Our organic cotton onesie is precisely what you need for those chaotic, glorious early months. Crafted from 100 percent organic cotton, it's breathable, buttery-soft, and genuinely lovely against delicate skin from day one.
Why Choose Our Organic Cotton Onesie
Properly Soft and Beautifully Made: Unisex design works splendidly for both boys and girls. The fabric feels rather good against sensitive skin, and honestly, it's the sort of thing that makes parenting just slightly less bewildering.
Fuss-Free Nappy Changes: Lead and nickel-free snaps paired with coconut insert panels mean you'll spend less time fumbling and more time actually enjoying your baby. We've thought of the small things so you don't have to.
Eco-Friendly and Ethically Made: Non-toxic, eco-friendly dyes mean you're not just dressing your baby, you're being rather kind to the planet. Crafted in India with genuine care and proper standards.
Unisex and Utterly Fetching: One glorious design that works for everyone. No need to buy separate versions or fuss about gendered nonsense.

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.
