The Sleepsuit That Actually Lets You Sleep
Right, so here's the thing. Most baby sleepsuits are rather earnest about their job, which is admirable if slightly dull. This one, however, features a grinning Shiba Inu escape artist and refuses to take itself seriously, rather like myself at parties. It's soft as a puppy's ear, built to withstand midnight wiggles and the occasional vanishing act from the crib, and made with a conscience—ethically and sustainably crafted because we do care about such things.
Why Choose Our Baby Sleepsuit
Fabulous Comfort: 100 percent organic cotton that feels like a gentle hug against delicate skin, all day and night.
Splendid Durability: Properly made to handle the rigours of midnight wakeups, snack demands, and impromptu escape attempts without showing the strain.
Ethically Made: BSCI and SEDEX certified, because we rather believe babies deserve clothes with a conscience.
Utterly Fetching Design: That smiling Houdini fellow really does make an appearance. He's rather good company at 3 a.m.
Product Details
Fabric: 100 percent organic cotton, 160gsm weight. Direct-to-garment application for long-lasting print quality.
Care Instructions: Wash at 40 degrees on cotton cycle. Do not bleach, tumble dry, or dry clean. Wash dark colours separately. Use 2 dot iron only, and avoid ironing directly onto the motif.

This sleepsuit rather deserves a place in your nursery. Parents do seem to come back for more, which we take as a compliment of sorts. Do add it to your basket before the little escape artists beat you to it.
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

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.
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.
