Love the shape and look of our Naomi medium-flow menstrual panty ? We decided to create a swimsuit version of our best-seller! Find the beautiful sexy and elegant lacing on the hips, the flattering cut, and the solid black color of the Naomi model in a bikini version!  

The Juliette menstrual swim bottom is super graceful and truly charming. Feminine and pretty, this menstrual swimsuit is just as pleasant to wear as it is reliable. Its black color lets you pair it with any swimsuit top. For a fun, mix-and-match look. 

This period swim bottom can be worn both at the pool and at the beach. It stands up perfectly to both saltwater and chlorinated water. It lets you enjoy a worry-free afternoon without fear of leaks or stains. You can swim and sunbathe with total peace of mind during your period..

What are the benefits of the Juliette model? Its protection is ultra-discreet and undetectable. No one can tell you’re wearing a menstrual swimsuit. The absorbent area holds your menstrual flow without swelling. It has a very high absorption capacity without shifting or changing shape. Plus, the swimsuit remains incredibly comfortable.

It’s also a highly effective and reliable protection that extends throughout the entire interior of the swimsuit. The flow is stored in the absorbent membrane and can’t escape. 

The absorption of this swimsuit is equivalent to two tampons. So this swim bottom is suitable for light flow or medium flow..  

The Juliette menstrual swim bottom is an excellent zero-waste alternative to tampons for swimming. Washable and reusable, the menstrual swimsuit is a healthy, long-lasting, and eco-friendly hygiene solution. 

Our Juliette menstrual swimsuit is available in sizes XS to XL. Feel free to check our size guide before placing your order. 

Finally, like all other Louloucup swimsuits, our Juliette swimsuit can be included in a custom bundle and paired with panties or a cup for a reduced price! 


Our Juliette swimsuit is made in China in a workshop that has been audited, particularly for its limited use of plastic. The manufacturing facility is ISO 9001 and BSCI certified, and the fabrics are FDA-approved. 

All the fabrics used are clean. They are not harmful to your health or to the environment.

How is our period swimsuit so effective?

Our Louloucup swimsuits feature a hygienic pad specially designed for water use. This pad absorbs menstrual flow even in water. It absolutely does not swell on contact with water. Despite its very high absorbency, it remains thin and invisible. No diaper effect, we guarantee it—you’ll be comfortable! No one can tell the difference between our period swimsuit and a regular swimsuit. 

The period swimsuit lets you go to the beach with total peace of mind without needing an internal product like a tampon, menstrual cup, or pad. No need to worry about possible leaks. You’re completely free to move! 

Retrouvez votre liberté pour tout l’été !

Session baignade à la mer, à la piscine, farniente au soleil, prenez plaisir à rester en maillot pendant vos règles !
Nage et bronzette sont possibles en toute liberté sans angoisse ni crainte. Aussi bien dans l’eau que sur votre serviette de plage, vous êtes entièrement libre de vos mouvements. Si vous connaissez un flux léger à moyen, vous n’avez pas à utiliser de protection interne en supplément comme un tampon, une coupe menstruelle ou une serviette hygiénique.

The Juliette menstrual swim bottom is no exception. To avoid any risk of yeast infections or unfortunate UTIs, remove your wet swimsuit and don’t keep it on for too long after swimming. This advice applies to both menstrual swimsuits and regular swimsuits. 


Washing the Juliette menstrual swim bottom: top tips


Just like its menstrual panty version (Naomi model), the Juliette menstrual swimsuit should be rinsed with clear water after use. This removes a good portion of the flow absorbed by the fabrics. You can then machine wash it with your clothes on a short cycle at 30°C (86°F). Let the swimsuit air dry and avoid using a tumble dryer.
