Love the shape and look of our Naomi medium-flow period brief? We’ve turned our best-seller into a swimsuit version! Find the same beautiful, sexy and elegant lace-up detail on the hips, the flattering cut and the solid black colour of the Naomi model in a bikini bottom! 

The Juliette menstrual bikini bottom is super graceful and truly charming. Feminine and pretty, this menstrual swimsuit is as lovely to wear as it is reliable. Its black colour means you can pair it with any bikini top for a fun, mix-and-match look. 

This period bikini bottom can be worn both at the pool and at the beach. It stands up perfectly to both salt water and chlorinated water. It lets you enjoy a relaxed afternoon without worrying about leaks or stains. You can swim and sunbathe with complete peace of mind during your period.

The advantages 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 menstrual flow without swelling. It has a very high absorption capacity without shifting or changing shape. The swimsuit also remains very comfortable at all times.

It’s also a highly effective and very reliable protection that extends across the entire inside of the swimsuit. The flow is captured in the absorbent layer and cannot escape. 

The absorption of this swimsuit is equivalent to two tampons. This bikini bottom is therefore suitable for a light flow or a medium flow

The Juliette menstrual bikini 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 period protection. 

Our Juliette menstrual swimsuit is available from size XS to size XL. Don’t hesitate to check our size guide before ordering. 

Finally, like all other Louloucup swimsuits, our Juliette bikini bottom can be included in a custom bundle and combined with panties or a cup at a reduced price! 


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

All the fabrics used are clean: they are harmless to both your health and the environment.

How is our period swimsuit so effective?

Our Louloucup swimsuits include a hygienic protection layer specially designed for going in the water. This protection can absorb menstrual flow even while you’re swimming. This absorbent pad does not swell at all on contact with water. Despite its very high absorbency, it remains thin and invisible. No diaper effect, we promise—your comfort is guaranteed! 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 having to use an internal protection such as a tampon, menstrual cup or sanitary pad. You don’t have to worry about potential 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 bikini bottom is no exception to the rule. To avoid any risk of thrush or an unfortunate urinary tract infection, take off your wet swimsuit and don’t keep it on for too long after swimming. This applies to both menstrual swimsuits and regular swimsuits. 


Washing the Juliette menstrual bikini bottom: top tips


Just like its period underwear version (the Naomi style), the Juliette menstrual swimsuit should be rinsed in clear water after use. This removes a large part of the flow captured by the absorbent fabrics. You can then pop the swimsuit in the washing machine with your clothes on a short 30°C cycle. Leave it to air-dry and avoid using a tumble dryer.
