Sarcasm Never Looked So Snuggly
You know those days when socialising feels like a full-time job and coffee is more necessity than pleasure? Yes, this is the sweatshirt for that. Delightfully sarcastic and fabulously soft, it’s like a warm embrace from someone who finds hugs a bit beneath them. Also features Grumpy Cat, patron saint of mildly annoyed souls everywhere.
Why Choose Our Womens Grumpy Cat Sweatshirt?
Fabulously Made: Crafted from 92 percent combed cotton and 8 percent lycra, it offers a splendid balance of stretch and softness. Ideal for everything from Netflix marathons to pretending your Zoom camera is broken.
Marvellously Flattering: Designed with a regular fit, this number flatters without showing off about it. Honestly quite fetching in a laid-back, couldn't-care-less sort of way.
Delightfully Low-Maintenance: It’s machine washable, which is terribly good news for those of us not blessed with live-in staff or boundless patience.
Responsibly Tailored: Produced with care in Estonia using Oeko Tex Standard 100 certified fabrics. Because comfort shouldn't come with a guilty conscience.

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.
