Less adjusting.
More swimming
That's the whole idea. Swimwear cut to stay where you put it, in colours that look like they've already had a good summer.

After
the swim
Salt on your shoulders, the long walk back up the sand, a towel big enough to lie on properly. That last part is the Rayas: striped cotton, 90 x 170 cm.
The Puerto short comes along for all of it. It's navy, with a proper drawstring at the waist, so the only thing you're adjusting is your plans for tomorrow.

FilmA morning in the studio
Made in our studio in Valencia
Costa Mira is a small studio in Valencia making swimwear and beach things: one-pieces that stay put when you dive, bikinis in sun-washed colours, swim shorts with a proper drawstring, and striped cotton towels for when you come out.
We think a swimsuit should be made for the part where you actually swim. So we cut ours from swim fabric made from recycled nylon, keep the shapes simple, and spend our time on what you notice in the water: a scoop back that stays put, sides you can tie, a drawstring worth the name.

- HipsAround the fullest part, feet together.
