Black, V-cut back, and a ruffle that emphasizes the neckline at the front: an ideal harmony for an elegant swimsuit.

The cut

  • Removable foams!
  • A wide ruffle borders the front neckline and ends at the shoulders.
  • Perfect for the beach in mid-season, as in the evening, worn with a skirt or denim shorts.
  • The cut has been designed to suit all cup sizes: A, B, C, D and E.
  • The fabric is sculpting for absolute wrap and comfort when you move.
  • The bottom is classic, not indented.

With its sculpting and shaping material, the chest is maintained and the curves sublimated.

Size advice
To choose your one-piece size, refer to your bottom size. For example if you take 36 in panties, take S in one piece.

In case of doubts or questions about the size, do not hesitate to write to us at

Chloé is 1.80m tall, has a C cup and wears a size 36 at the bottom, so an S in one piece.

Fabric & Care

Posidonia's objective is to use a fabric that contributes to cleaning the oceans and the environment, but also very elegant and comfortable to free women from any constraint of movement. An eco-responsible jersey is also a sustainable jersey, which is why I have chosen the highest range of European fabric made up of waste such as fishing nets and plastic bottles.

The sea and the salt do not alter your swimsuits if you rinse them with fresh water after each use. Let it dry flat or laid out on its own.

Hand wash your swimsuit. You can wash it in the washing machine at the end of your vacation, on a delicate cycle (max. 30 degrees), with a non-detergent detergent, without spinning or drying cycle.

The chlorine resistance index of our materials is very good. The colors, however, are more delicate.
