One piece n°5 - Black Striped

$61.00 USD $120.00


The leotard for dancing in water!

The cup 

  • A square neckline and a bra effect
  • 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 swimwear is lined with our soft material 

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 the cleaning of 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.

84% Ecoyarn PES. 16% Elastane.
Weight: 200gr
Labels: OEKO-TEX Standard 100. Global Recycled Standard.
Fiber recycling and fabric manufacturing: Spain. The energy used at the plant is solar. Ecological printing. Kilometer 0 between bottle collection and processing plant.

🌞 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.
