One Piece n°1.1 - Satin Mediterranean Blue

$64.00 USD $120.00


The new version of the flagship piece of the eco-friendly collection, the one-piece with the low back. Less low-cut than the previous one.

The cut

  • Its suggestive cut-out on the side does not exclude a pleasantsupport and provides a real freedom of movement.
  • The swimsuit is lined with our softest material.
  • Adjustable straps that attach in 3 ways by a system of Italian-style knots: straight, crossed behind the back or behind the neck.
  • No iron or plastic (let's avoid micro-waste) to adjust the straps but knots. The knots are small and pleasant to wear. On the adjustment side, the iron eyelets slide very poorly on swimsuit materials and tend to loosen the straps too quickly; on the contrary, the knots do not loosen when you are moving.

Size advice
To choose your One-piece size, refer to your Bottom size. For example, if you are a size 36 in knickers, take a size S in One-piece. The straps are adjustable and will fit your top.
This swimming costume fits normally. If you are over 1m70 and not sure which size to choose, go up a size.

If you have any doubts or questions about the size, please contact us at

Our models

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.

🌞 UV protection SPF50


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.
