Designed using uniquely developed fabric that allows sunlight to pass through, resulting in an even & golden tan.

Made with all women in mind to be flattering, elegant, lightweight, and breathable, without sacrificing comfort.



Our bikinis dry up to 7 times faster than regular swimwear. This means that you no longer have to stay in a wet bikini, which is great for preventing UTIs - a huge pain.

They are unlined but not see-through when worn.


how does it work?

Our advanced “micro-tan” technology means that sun rays can pass through thousands of small holes of the fabric onto your skin, thus minimising and preventing harsh tan lines, resulting in an all-around, golden tan. We have created the perfect balance to ensure that enough light passes through the micro-perforations of the fabric whilst still ensuring good coverage

I didn't believe it at first, but I was in the midday sun for 2-3 hours and actually didn't get an impression at all. I am thrilled. Through that the bikini has long straps to lace, you can wear many different variations with it! 🤩 worth it in any case 💯

Clemens Maggio

The top is very good from the processing. It is not transparent. Very comfortable to wear. From the size you can take this where you normally have. In the sun I could not yet test the bikini.

Jasmine Frami

Fits very well and black always looks good;)

Cristina Hodkiewicz

This swimsuit set is amazing for its price. The quality is good and the bottoms are super cute on. They look even better in person!

Jenny Turner

Super nice top, fits well and is opaque when worn.
