Tan-Through Long Sleeve Shirt – Blue Mandala
Experience the Sun Differently with the Smarttan Tan-Through Blouse
Embrace the sun with confidence and elegance in our Smarttan long-sleeved tan-through blouse. Crafted from an ultra-thin, stretchy material, this innovative fabric acts as a replacement for traditional sunscreen, letting you tan naturally and safely during all your outdoor activities, from casual strolls and beach days to sporting events.
Key Features:
- Sunscreen Alternative: Allows up to 70% of UV rays to pass through, promoting a natural tan while ensuring skin protection.
- Performance Fabric: Composed of 80% polyamide and 20% elastane for exceptional stretch and rapid-dry capability, allowing you to swim comfortably and dry off quickly.
- Elegant Design: Features a skin-colored lining at the chest, offering the freedom to forgo a bra while ensuring modesty and comfort.
Why You'll Love It:
- Breathable Comfort: Thin, perforated fabric ensures excellent airflow, keeping you cool as you enjoy the sun’s warmth.
- Versatile Style: Pair with matching patterned mini leggings for a chic, sporty look that moves with you.
- Effortless Tanning: Achieve a healthy tan without the fear of sunburn, mimicking the effects of sunscreen without the hassle.
Note: While highly protective, the fabric does not block 100% of UV rays. For optimal results, we recommend pairing with a suitable sun protection oil to achieve an even tan.

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. Nothing loud — just quietly brilliant pieces made to last.
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.
