Marvel at a Marvellous Tan — Without the Pesky Lines

If you've ever thought, “Good heavens, how did that strap mark get there?” — you’re in excellent company. This fabulously clever long sleeve bikini set lets the sunshine in while keeping your skin delightfully protected, so you can frolic about with style and... well, significantly fewer tan lines.

Why Choose Our Tan Through Bikini Set?

Light as Air Fabric: Innovative open-knit design allows sunlight through for an even tan, while giving you decent SPF and UV protection — you know, the useful sort.
Day-Long Comfort: With a gently supportive long sleeve top and bottoms of your choosing, this set was clearly made for meandering beach wanders and accidental naps by the shore.
Customisable Style: Whether you're in the mood for more coverage with high-waisted bottoms or feeling gloriously minimalist with string ties, it's entirely up to you.
Quite the Sustainable Gem: Lovingly made in Scotland with leftover fabric upcycled into cheery bobbles and handy pouches. It's eco-conscious and just a tad smug about it.

Product Details:

Sizes: Available in S, M, or L — marvellously accommodating, if we do say so.
Fabric Composition: 81 percent breathably clever polyester and 19 percent Lycra for that just-right stretch.

Secure your spot in the sun with a suit that plays brilliantly at both being stylish and sensible. Go on, treat yourself to a little vitamin D and a proper tan. Snap yours up today before someone slightly more organised gets there first.

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.

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.

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!
