Leggings So Lovely They Might Upstage Your Kid (Briefly)

Ah, small children. Endlessly energetic, occasionally theatrical, and alarmingly stylish by accident. Dressing them is rather like running a fashion show during an earthquake. Enter these gloriously comfy, fabulously flexible leggings — ready for nursery performances, snack-fuelled adventures, or impromptu living room tap routines.

Why Choose Our Kids Cotton Stretch Leggings?

Splendid Comfort: Made from 95 percent Oeko-Tex certified cotton and a dab of elastane, these feel like a hug from a very gentle cloud. Stretchy enough for tree climbing, soft enough for sofa flopping.

Utterly Fetching Design: Uniquely gender neutral and pleasing on the eye, these leggings let your little whirlwind express themselves without looking like a walking Pinterest board.

Grows With Them: Thanks to clever double sizing, they keep up with growth spurts that arrive with no warning and zero apology.

Properly Crafted in Europe: Made with an admirable degree of care and attention to detail. Because disposable fashion is rather passé, don’t you think?

Product Details:

Fabric Composition: 95 percent cotton, 5 percent elastane

Certification: Oeko-Tex Standard 100 certified, lovely and safe for sensitive skin

Care Instructions: Machine wash inside out at 40°C, reshape gently while damp. Expect a modest 5 to 7 percent shrinkage — nothing dramatic, we promise.

Fit: Designed with flexible sizing to adapt as they sprout skywards

Ready for Everyday Adventures

Pop a pair in your cart and let your child take on the day looking splendidly individual and marvellously comfortable. Rather like a very stylish superhero without the cape.

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!
The brands we work with all have a chat option, and they love to chat!

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!

All prices in lovely British pounds £ GBP, though international chaps will see converted prices.

Any payment pickle? We're here to help sort things out! Contact us

We are Sostter

We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.

Read All About Us >

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.

Sostter partners with independent brands that intrigue, inspire, and bring something genuinely different to the world of fashion, design, and living. Join us!
