Let Your Little One Take Flight
Here's the thing about children's costumes: they either spark pure joy or they gather dust in a cupboard, rather like my academic papers. This batwing set, we're delighted to say, falls firmly into the former category. Crafted from 100 percent organic cotton that's soft as a whisper and gentle on delicate skin, it's the sort of outfit that makes dressing up feel rather marvellous.
Why Choose Our Batwing Costume Set
Splendidly Soft Fabric: One hundred percent GOTS certified organic cotton means your child stays comfortable whether they're swooping around the garden or navigating a crowded Halloween party.
Kind to Sensitive Skin: Environmentally friendly AZO free dyes ensure nothing harsh touches delicate skin. Rather good for peace of mind, that.
Easy Care: Machine washable at 30 degrees because, let's face it, costume adventures get messy. No faff required.
Complete Look: The set includes a cosy batwing shirt and a charming mask that brings the bat character gloriously to life. Fangs not included, but honestly, teeth are optional when you've got this much style.
Product Details
Size Range: Available from 6 months through to 8 years, so there's rather a lot of growing room here.
Perfect For: Halloween parties, fancy dress days, imaginative play, or any occasion calling for a bit of night flight magic in the wardrobe.
Materials: One hundred percent organic cotton with AZO free dyes.
Care: Machine wash at 30 degrees.
Order now and give your child the gift of becoming a bat. They'll be the talk of the playground, and you'll feel splendidly virtuous about the organic cotton bit.

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!

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.
