Sumba 💜

In love with this swimsuit!
The fabric is super soft and it stays in place while doing jumps and tricks , exactly what a kitegirl needs ✨

L.M. (Noblesville, US)

Beautiful color and coverage

This is such a beautiful suit. I'm usually a small or medium in swim tops and small in bottoms, so I went by the size chart measurements and got a medium for both. The bottoms are definitely cheeky but it gives it a little bit of a sexy silhouette without being too much. I can't wait to wear this!

Elizabeth lubis (Jakarta, ID)

Fit me well

Good fabrics. The color is Suitable for my skin!

Naia Sohl (Denpasar, ID)

Great for surfing

Love that they actually stay on when I’m surfing and I can wear them when I’m on the beach as a normal bikini.

So glad you love it! Secure for surfing and stylish for the beach—best of both worlds! Enjoy the waves! ✨

C.M. (Évry, FR)

My fav bikini bottom

It was my first piece from OSB and now with the women rash guard it is my favorite swimwear.
Very flattering fit and confortable. I love it!

Tides of Rest: Reclaiming Slow Living Through the Rhythm of the Sea

We weren’t made to move in straight lines. We weren’t meant to wake with the same energy every morning, push through fatigue, or stretch ourselves thin across endless to-do lists. And yet, so many of us do—ignoring the quiet calls from our body to slow down, soften, and be still.
