Timeless elegance. Retro, beautiful, we love it!

The cut

  • The neckline remains very light on this model. It is suitable for all cup sizes.
  • Adjustable straps with an Italian knot system.
  • No iron or plastic (let's avoid micro-waste) to adjust the straps but knots. The bows are small and pleasant to wear. As far as adjustment is concerned, the iron eyelets slide very poorly on swimwear materials and tend to loosen the straps too quickly; on the contrary, the knots do not loosen when you are moving.
  • The swimsuit is lined with our softest material.

It is sculpting and sublimating! Absolute comfort. Perfect for paddle boarding!

Size advice
To choose your size of One-piece, refer to your size of Bottom. 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.

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.

For Khaki and White bi-materials:

- The main fabric is made of 78% recycled polyamide and 22% elastane.
- The striped fabric of 90% Ecoyarn Polyamide and 10% elastane.

For the Coral bi-material:

- Main fabric is 85% Ecoyarn PES and 15% Spandex.
- The striped fabric of 90% Ecoyarn Polyamide and 10% elastane.

Labels: OEKO-TEX Standard 100. Global Recycled Standard.

🌞 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 machine at the end of your vacation, in a delicate cycle, with a nut of non-detergent detergent, without a spin or drying cycle.

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

Super produit, belle matière et bien coupé mais ne me va pas car petite poitrine

Une Pièce 7.0 - Kaki & Noir

Pas encore testé mais déjà adoré

Je ne me suis jamais sentie aussi belle dans un maillot de bain, sculptant sans être trop serré, un décolleté que je n'imaginais pas être aussi beau (habituellement je n'aime pas l'aspect "tombant" de ma poitrine, là elle est très bien mise en valeur)
Pas encore testé dans l'eau/activité aquatique (je fais du kite) mais le maintien est bon donc je ne doute pas de son efficacité.
Je recommande vivement !

Magnifique et hyper confortable

Vraiment magnifique ce maillot ! La coupe est parfaite, bien galbante et fait un beau décolleté ! Matière hyper confortable, un must have pour l'été ! Direct dans la valise pour les vacances !


Ce maillot est une beauté éco-responsable!!😍🙏
