Laura is a hit with all our users. You’ll have fun mixing and matching it with your various bikini tops (black or colorful pieces!)

Its high-waisted cut enhances your curves, the lace-up back is unique, and the protection remains invisible. Our Laura period bikini bottom has it all!

It’s perfectly suited to managing a light to medium flow. It absorbs the equivalent of 2 tampons. Very comfortable and pleasant, you’ll enjoy wearing this swimsuit at the beach or poolside without worrying about leaks!

Laura is available from size XS to 2XL. 

The Juliette period bikini bottom ❤︎

The Juliette period bikini bottom is a very pretty period swim brief with beautiful detailing at the hips.

Juliette is available from size XS to 2XL. 

The Manon period bikini bottom ❤︎

The Manon period bikini bottom is ultra-basic, and that’s exactly why we love it! Manon is a very simple period swimsuit bottom: a classic brief cut in plain black.

DID YOU KNOW?

A menstrual bikini bottom is washable and therefore reusable. Just like period underwear, a period bikini bottom can be worn for years (5 to 7 years) if it’s properly cared for and washed. It’s a truly eco-friendly, long-lasting menstrual product and an excellent investment!

☂︎ How do menstrual swimsuits manage to hold blood without leaking? ☂︎

It’s thanks to the layering of technical fabrics that we can pull off this feat: absorbing menstrual flow and locking it in so it doesn’t escape, even when you’re in the water. 


  • Louloucup period swimsuits are made with a super-absorbent layer. This layer holds your menstrual blood without swelling or bothering you. It’s built into the core of the swimsuit.

  • Then underneath this layer, on the outside, a waterproof fabric blocks any leaks. You’re totally secure! Your swimsuit protects you for several hours while staying thin. Comfort, security and peace of mind are guaranteed.

That means no blood in the pool, no leaks in the sea and no stains on your beach towel! Enjoy a refreshing swim at the pool, the sea, the ocean, the lake or the river. Anywhere, anytime thanks to our period swimsuits!


Far better than a tampon with questionable ingredients, and more convenient (for some) than a cup, menstrual swimwear is becoming the ideal choice. The equivalent of period underwear, menstrual swimsuits are reusable, washable, effective, and above all, stylish.

And what about heavy or haemorrhagic flow?

Our swimsuits are designed to absorb the equivalent of two tampons. For women with a heavy or very heavy flow, we recommend wearing the Loulou menstrual cup along with the swimsuit. This way, you’ll be fully protected. There’s no risk of leaks with this double protection, which is safe while respecting your privacy.

Do you have a heavy or very heavy flow? With our heavy to very heavy flow period panties, you’re protected for a full day or night. Our styles have an absorbency equivalent to 5 tampons! Don’t hesitate to add a few pairs to your cart when you order your favourite period bikini bottom! 😉

DID YOU KNOW? 

A menstrual bikini bottom is different from period underwear. A period bikini bottom is made to go in the water and stay in place without becoming waterlogged. Period underwear is not designed for swimming; it doesn’t have the right fabrics. Swimming in period panties would be just as unpleasant as swimming in regular underwear.

Caring for your menstrual bikini bottom

Just like period underwear, period bikini bottoms are easy to care for. By following the steps below, you’ll keep your bikini in great condition and be able to wear it for many years:

After your swim or when you get back from the beach, make it a habit to rinse it in clear water to remove blood as well as any sand, salt or chlorine residue.

Avoid using rich soaps or other harsh household products when rinsing. They can prematurely damage your swimsuit.

Then pop your swimsuit in the washing machine with the rest of your clothes, preferably on a short cycle at no more than 30°C. High temperatures can damage the performance of the absorbent layer.

Just like with period underwear, no tumble dryer here! Air drying is recommended.

Fall for our TEEN styles and enjoy swimming and all your water activities with total peace of mind from size XXS upwards! 😎

Taking a dip on your period? Yes, absolutely yes!

With a period bikini bottom, freedom is yours! In summer, during your period, at home or on holiday, this hygienic bikini bottom will become a must-have. 


This reliable, secure period swim brief lets you enjoy yourself, sunbathe and take a dip while avoiding that infamous irritating tampon. What a mental load off! These period swimsuits are a real step forward and a move towards more freedom. Because our periods should never hold us back in life, Louloucup works every day to offer you effective, body-friendly solutions.
