Pickup currently not available
Flatter Your Form and Pocket Your Phone
Just imagine — leggings that actually stay up, flatter your curves, and even carry your keys without turning you into a crumpled kangaroo. These inky black wonders have side pockets discreet enough for a card or snack, but useful enough to make you question ever wearing anything else.
Why Choose Our Black Leggings with Side Pockets?
- Side Pockets: Cleverly placed and delightfully subtle for essentials like your phone, lip balm, or mildly disappointing muesli bar
- Adjustable Waist: Inner drawstring lets you tighten or un-tighten depending on how ambitious your lunch was
- Comfy Compression: The stretchy-but-not-too-stretchy fabric gives a gloriously snug fit that supports without smothering
- Squat-Proof Confidence: Keeps everything under wraps whether you’re bending, stretching or running late again
- Flattering Fit: Carefully crafted seams that seem to know your angles better than you do
Product Details:
- Material: 80 percent nylon and 20 percent spandex for bounce-back brilliance
- Fit: True to size with 5 to 8 cm of natural stretch
- Model Wears: Size M (63 cm waist and 80 cm hips laid flat)
Slip into these fabulously made leggings now and feel delightfully stylish by tomorrow
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!
The brands we work with all have a chat option, and they love to chat!
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!
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.
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.
