Now, **having your period in summer** is no longer such a pain! Our periods used to really ruin things for us and crash the party, especially when we had an afternoon at the pool with friends planned!


Today, the various period product brands are adapting and offering more and more solutions that are healthier, simpler and more eco-friendly. Bye-bye to the single-use, disposable, polluting tampon! These days, to swim and sunbathe with total peace of mind, women and teens can turn to the menstrual cup or the period swimwear.


The one-piece or two-piece menstrual swimsuit is the eco-friendly, economical, easy and stylish solution for managing your period while swimming. Just like with menstrual panties, the key is to choose a menstrual swimsuit model suited to your flow. How do you choose a menstrual swimsuit? Where can you buy the best menstrual swimwear? How do you know your flow level? Louloucup helps you find the best menstrual bikini bottom.

One-piece or two-piece swimsuits that work for light to medium flows

A one-piece period swimsuit (or period bikini bottom) can be suitable for a light to medium menstrual flow. At the moment, brands offering period bikinis only have models that can handle this type of flow.

Period swim bottoms are made with several different fabric layers. An absorbent layer captures the blood and holds it, a membrane inside the swimsuit stores it without swelling, while another outer fabric prevents sea or pool water from saturating the swimsuit. In short, this layering of technical fabrics is very effective!

And what about heavy flows?

For anyone with a heavy flow or very heavy flow, we recommend wearing a menstrual cup in addition to your period swimsuit.

The cup is really ideal for collecting even the heaviest periods. That way, you’re sure to avoid leaks, dampness and bad odors. You can swim with total peace of mind and enjoy the pool or the beach without worrying about a thing!

How do I know if a menstrual swimsuit is right for me?

To be completely confident in your period bikini bottoms, you need to know your exact menstrual flow. To do this, you’ll need to take the time to really get to know your period and observe how you use your usual period products.

How many **tampons** do you use per day?

Do you need to change often, or can you go half a day or even a full day without changing your pad or tampon?

If you use a cup, it’s even easier to know your flow. Does it fill up quickly? Do you feel the need to empty it often?

Do you use more than four tampons a day? If so, your flow is quite heavy.

Handy tips for choosing the right menstrual bikini bottom

Pay attention to the brand and user reviews. Take the time to do a thorough comparison between the different styles of menstrual bikini bottoms and menstrual swimsuits.
Check the size and how the brand fits. It’s important that your menstrual swimsuit is snug so it can protect you as effectively as possible.

Look closely at the fabric composition and the delivery times. Finally, what will obviously make all the difference is the style itself. Do you want a fairly classic one-piece swimsuit, a two-piece swimsuit, or just menstrual bikini bottoms you can pair with any bikini top?

Is a menstrual swimsuit right for me?

A period bikini bottom or one-piece swimsuit is right for you if:


  • you want external rather than internal protection (like tampons or cups),

  • you’ve made the switch and fallen in love with **period panties**,

  • you have a light or medium menstrual flow,

  • you’re a big fan of swimming and sunbathing and absolutely don’t want to miss out on those wonderful summer moments!
