Smarttan Long-Sleeve Shirt: Enjoy the Sun with Innovative Protection
Introducing the Smarttan Long-Sleeve Shirt, crafted for those who love the sun but prioritize skin safety. This unique shirt is designed with an ultra-thin, stretchy tan-through fabric, eliminating the traditional need for sunscreen. Whether you're walking, exercising, or relaxing on the beach, enjoy sun exposure comfortably and confidently.
Features and Benefits:
- Tan-Through Technology: Experience up to 70% UV ray penetration with our special fabric that allows for a natural tan without sunburn risks, offering a "fabric sunscreen" effect.
- Multi-Functional Use: Perfect for both land and water activities. Swim confidently, knowing the shirt dries within minutes.
- Comfort and Flexibility: Made of 80% polyamide and 20% elastane, ensuring a comfortably stretchy and breathable fit that adapts to your lifestyle.
- Stylish Privacy: A thin, skin-colored lining across the chest area allows you to wear it without a bra, providing coverage while disguising the fabric's sheer nature.
- Quick-Drying and Breathable: Perforated fabric promotes airflow and dries quickly, keeping you cool and comfortable.
Important Usage Tips:
Please note that while our fabric significantly reduces the risk of sunburn, individuals with sensitive skin should gradually test their exposure. For a balanced tan, consider using sunscreen or tanning oils suitable for your skin type, as no tan-through fabric allows 100% UV penetration.

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.
