Women's One-Piece Swimsuit with Open Back and Shorts
Open Back One-Piece Swimsuit – Sporty, Supportive, and with a Detail That Changes Everything
Freedom of movement, true support, and a back that shows off: for those who don’t want to choose between practicality and style.
How many times have you looked for a swimsuit that didn’t just seem “functional”? This one-piece swimsuit with a circular open back solves exactly this. Already chosen by thousands of active women, it combines the support of a sporty swimsuit with an unexpected aesthetic detail: the circular opening on the back that enhances the silhouette without revealing too much. The shaped light blue side inserts slim the hips, the integrated shorts provide coverage without squeezing, and the high-elasticity fabric follows every movement — in the pool and out.

The detail of the open circular back — the highlight of this swimsuit.
Why Choose It?
- Circular open back: a detail that elegantly enhances the back without sacrificing the support of the straps.
- Integrated shorts: covers and supports with freedom of movement — no swimsuit riding up, no discomfort in or out of the water.
- Shaped side inserts: create a slimming visual effect on the hips, naturally enhancing the figure.
- Supportive round neckline: keeps everything in place even during strokes — zero adjustments needed.
- High-elasticity fabric: adapts to the body without compressing, dries quickly, and withstands repeated use in water.
Details That Make a Difference
- Removable internal cups: customizable support according to your preference.
- Wide and stable straps: distribute weight evenly, avoiding pressure on the shoulders.
- Internal lining: double layer in the chest area for greater coverage and support.
- Chlorine, salt, and sunscreen resistant: maintains shape and color even with frequent use.

How to Match
Pair it with a light black or blue sarong for poolside, or with white flat sandals for a walk after swimming. The detail of the open back makes it interesting even with a flowy linen skirt for an aperitif by the sea.
