I. Period swimwear: a revolution for swimming on your period

💦 What exactly is a period swimsuit?

The period swimsuit—also called a menstrual swimsuit, menstrual bikini, or period swim panty—is an alternative to traditional period products for enjoying the beach or pool during your period.


Designed with multilayer technology, these special swim briefs absorb and lock in flow, preventing it from leaking into the water.

💦 How does a period swimsuit work?

The system is made up of several layers: one layer absorbs the blood, another holds it in, and a third prevents it from leaking out.


The first layer in contact with your skin absorbs, the second has a high capacity for holding flow without swelling or shifting, and the third, outer layer is waterproof. This last layer keeps water out.

A period swimsuit is ideal for managing, absorbing, and capturing light to medium menstrual flow for 4 to 6 hours. So far, no period swim bottoms can effectively contain a heavy or very heavy flow without risk of leaks.

Menstrual bikinis can be used in any aquatic situation. Whether you’re swimming in chlorinated pools or the ocean, they provide reliable protection. You can swim, have fun, do water aerobics, or enjoy the waves without worrying about leaks.

The Juliette period bikini bottom 😍


  • Absorbent swim bottom for light to medium flow (about the equivalent of 2 tampons).

  • Juliette stands up perfectly to both salt water and chlorinated water.

  • This period bikini bottom is the aquatic, waterproof version of the pretty Naomi period panty for medium flow. Don’t hesitate to add that to your cart too!

  • Available from size XS to 2XL.

  • Price: €28.90 before the custom bundle discount. Order other products from the shop and Juliette drops to just €22.90!

💦 No more tampons at the pool: freedom regained

Traditional period products can be a hassle at the pool or beach. Here are the main drawbacks:

  • ⛱️ Tampons are hard to insert outside and tough to change discreetly. Changing your tampon in a crowded beach bathroom isn’t easy—the space is cramped and not always clean. Plus, there’s sand.

  • 🦠 Risk of toxic shock syndrome. If you don’t change your tampon or leave it in too long, you increase your risk of TSS. Even though this infection is very rare, it is serious. So you need to take it very seriously and wear your tampon for a maximum of 4 to 6 hours.

  • 🩸 Pads can leak in the water. Disposable pads are really impractical at the pool or beach. Not only are they visible, but they’re not waterproof at all and swell up at the slightest hint of moisture! Instant diaper effect!

  • ♻️ Pollution from disposable menstrual products. Pads and tampons generate a huge amount of non-recyclable waste—there’s no denying it. It’s harmful to the planet and the oceans. Choosing reusable products (underwear, swimsuits, or cups) is an eco-friendly, responsible, and conscious choice, a real step to help the planet!
  • 😓 Physical and mental discomfort caused by a visible tampon string or the unpleasant feeling of a pad.

The period swimsuit transforms your swimming experience. No more stress. No more worrying about your period. No more embarrassment. You can fully enjoy the moment without fear of leaks, feeling totally confident. 



Period swimwear changes your relationship with your period. That time of the month is no longer as restrictive because you have the right tools to manage and control it.

💦 Say goodbye to discomfort: swimming during your period is now easy

The taboo around periods is fading thanks to period swimwear. You no longer have to skip the beach or the pool. Discreet technology lets you fully enjoy water activities: surfing, windsurfing, jet skiing, and more.


Period swimwear adapts to all your outings. On a beach holiday, at swimming lessons, or for an afternoon at the pool, it gives you reliable protection. You no longer have to plan your days, holidays, or weekends around your period.

II. The unmatched benefits of period swimwear

😎 Comfort and safety: major advantages


The period bikini offers ideal comfort for swimming. You’ll almost forget you’re on your period, thanks to its soft lining and perfect fit. No irritation or discomfort during water activities.


Leak-proof technology guarantees maximum safety. The wicking liner quickly absorbs blood, while the 3D mesh locks it in. The waterproof layer stops any leaks, even in the water. Enjoy the pool or the beach with total confidence.


=> A comfortable and reliable choice.

😎 Eco-friendly and cost-effective: the smart choice

Choosing a reusable period bikini bottom significantly reduces waste. You avoid throwing away thousands of tampons over the years. It’s a sustainable solution that protects the planet while staying practical. Just like period panties, well-cared-for period swimwear will last for many years. It’s an ethical, long-term choice.


Period swimwear is also a budget-friendly option.

  • The unit price can seem high, but you should see it as a real investment.
  • Over several years, it actually costs less than disposable products. You quickly make back your initial investment thanks to its long lifespan.
  • And we really can’t say it enough: at Louloucup, our already low unit prices can drop even further thanks to our custom bundle.

III. Different types of period swimwear to fit every need

🌸 One-piece, bikini, high-waisted: find your style

Period swimwear comes in various styles to suit all body types. You can choose between a one-piece, bikini, or high-waisted models depending on your aesthetic preferences and activity.


Teens can also enjoy the freedom of period swimwear, with designs tailored to their body shape and specific needs. Each style offers a balance between protection and comfort.

A one-piece provides perfect support for swimming. It’s a bit shaping and will be appreciated by those who feel bloated during their period.

A one-piece swimsuit can also double as a bodysuit under shorts or a sarong. Super practical for vacations.

The bikini lets you mix and match tops and bottoms according to your preferences and style. This absorbent swim bottom is discreet and thin.

High-waisted styles shape your tummy and are a great fit for A-shaped bodies. They provide support and a secure, all-around protected feeling.

Styles with wide straps provide effective support for the bust.

Asymmetrical cuts add energy to V-shaped figures.

OUR TIPS


Pick your swimsuit based on your activity and body type. For swim class, go for a one-piece with a racerback. For the beach, a colorful bikini or high-waisted bottom combines comfort and style.

🌸 Options for light, medium, or heavy flow

Period swimwear is suitable for light to medium or normal flow. For heavy or very heavy flow, we recommend adding a menstrual cup or menstrual cup to your period swimwear to avoid any unwanted leaks.

IV. How to choose and properly use period swimwear

🏊🏼‍♀️ Find your perfect fit: sizing guide

A quick look at our size guide will help you choose the right size. We strongly recommend checking it before confirming your order. Measure your bust at the fullest point, your waist at the narrowest point, and your hips at the widest point.


Our tip:

For period swimwear to work properly, it needs to fit well. A good fit guarantees both effectiveness and comfort. The bikini should follow your curves without digging in or feeling too tight. Make sure the leg elastics stay in place without pinching. If you’re between two sizes, choose the smaller one to avoid leaks.

🏊🏼‍♀️ First use: practical tips

Wash your period swimwear before first use to activate absorption. Wear it like regular swimwear, making sure it fits well. Rinse after each swim and machine wash at 86°F (30°C) without fabric softener.

FAQ – period swimwear

Can you pee while wearing period swimwear?

Some menstrual swimsuits are designed to absorb light urinary leaks, as well as periods and everyday discharge.

These swimsuits feature multi-layer protection: a layer of organic cotton, an absorbent layer of hemp fleece, and a waterproof PUL layer. They can be worn for up to six hours and can be paired with a menstrual cup if necessary. It’s important to rinse the swimsuit after use and wash it at a low temperature.

How long does period swimwear last?

The lifespan of menstrual swimwear is about 5 years, or even 5 to 7 years depending on the model. To make it last, it’s important to follow certain care tips.


It’s recommended to rinse it in cold water after each use and machine wash at a low temperature (no more than 30°C/86°F) with a gentle detergent. Air drying, away from direct heat, is best. Proper care helps preserve fabric quality and maintain its effectiveness.

Period swimwear: how to deal with odors and hygiene?

Menstrual swimsuits are made with natural antibacterial fabrics like bamboo fiber.


The first layer of fabric is breathable and quick-drying, allowing fluid to pass inside the swimsuit while keeping the surface feeling dry. The period swimwear allows blood to flow freely, reducing blood stagnation in the vagina and limiting bacterial growth.


How is period swimwear different from period panties?

Period swimwear can be fully submerged and stays in place in the water (it doesn’t move and sits snugly against your skin) while holding menstrual flow.
Period panties are not designed to be worn in the water. In that respect, they’re just like regular underwear. The fabrics used in period panties aren’t suitable for swimming; however, once you’re out of the water and want to feel dry, don’t hesitate to slip on a period panty under your sarong!
