One Piece n°8 - Garnet

$47.00 USD $111.00

The cut 
  • The first fixed strap jersey of the brand!
  • The asymmetrical single strap: so perfect for the beach or for the evening, worn with a skirt or jean shorts
  • The beautiful asymmetry of the neckline is suitable for A,B,C cups but also for D cups, as you can see on our Sigrid model
  • The swimsuit is lined with our soft recycled material
  • The bottom is classic, not indented

The fabric of this model shimmers slightly in the sunlight. It is a second skin fabric, not sculpting (sculpting fabrics are usually our matte fabrics).

Size advice 
To choose your size of One-piece, refer to your size of Bottom. For example, if you are a size 36 in panties, you should choose a size S in One-piece. The straps are adjustable and will fit your top.
This swimming costume fits true to size. 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

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.

82% Recycled Polyamide. 18% Elastane.
Weight: 175gr.
Bi-directional stretch (marries muscles & movements: great sensation)
Label: OEKO-TEX Standard 100.
Italian fabrics.

🌞 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 only, never machine wash.

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

Très satisfaite

Je suis très satisfaite de mon achat. Belle matière et surtout très belle couleur pour ce maillot. Taille légèrement petit, je conseil en cas de doute de prendre la taille au dessus

Top !

Le maillot taille très bien, la qualité est excellente. Très contente de mon achat

Génial !

Très contente de mon achat, la matière est top, le maillot est très confortable, la couleur & la forme sont magnifiques et ça fait du bien d'acheter "responsable".
Le seul bémol : j'ai une forte poitrine et le maillot glisse là où il n'y a pas de bretelle. Je fais un 85E et un 36/38 j'ai pris la taille M.

Achat de 2 maillots

Très contente de mes 2 achats : un une pièce et un deux pièces. Les modèles sont d’une excellente qualité, ils gainent très bien mais sans marquer non plus … la matière est résistante et on sent de suite que la qualité est très bonne
Les couleurs sont également magnifiques, satinées juste comme il faut pour briller 🤩 sur la plage 🏖 !!
