Today we’re helping you find and choose with our super detailed teen period swimsuit comparison! On the agenda: our opinion, our favorite style, customer feedback, our prices and all our tips to help you find the swimsuit that will suit your teenager best!

🩱 The teen menstrual swimsuit, an effective protection

After the period underwear, menstrual swimwear has, summer after summer, convinced more and more women and also more and more teen girls of its effectiveness. It may be surprising, but just like washable, reusable period panties, menstrual swim bottoms offer high absorption while being very reliable.

How does a period swimsuit work?

Once you’re in the water, your period blood doesn’t escape, dilute, or leak out of the period swimsuit! Your menstrual flow is held securely in place by the swimsuit’s absorbent lining, which is absorbent on the inside and waterproof on the outside.

Does a period swimsuit absorb all types of flow properly?

With a period bikini, there’s nothing to worry about!

Period swimwear is effective at holding light menstrual flow and normal to medium menstrual flow.
However, it’s trickier for heavy or very heavy flow. In that case, we strongly recommend using an additional protection: a cup or menstrual cup is the best option. You can of course also use a tampon, a menstrual disc or a menstrual sponge.


At the moment, there is still no period swimsuit that’s efficient enough to absorb a heavy or very heavy flow without leaking.

Fall for our Louloucup teen bikini bottom: Manon!


  • This pretty bikini bottom is highly absorbent: it handles a light to medium menstrual flow perfectly. It captures the blood and locks it into its absorbent layer so it doesn’t escape into the water.

  • The Manon period bikini bottom is available in XXS to suit the slimmest teens.

  • The Manon teen period bikini bottom is €22.90 before discounts with our custom sliding‑scale bundle and promo code! A great opportunity to gear up without breaking the bank!

  • Manon has a super basic, simple look so it goes with any bikini top. You can switch up your bikini as you like!

  • Just like regular period underwear that you wear every day, the Manon period bikini bottom is worn, then rinsed in cold water before being machine-washed at 30°C. Let it air dry and avoid direct sunlight! ☀️

🩱 Teen period swimwear comparison: how to choose?

Let’s go back over the different criteria you need to know before buying a period swimsuit for a teenager. In short, you need to consider: 

  • the price of the period swimsuit and the different possible deals (sales, promos, bundles, etc.), 
  • where it’s made, 
  • customer reviews, 
  • menstrual flow, 
  • the style of the model.

Price of a teen menstrual swimsuit

It’s obvious: the price of period swimwear or a period bikini bottom is higher than a box of disposable tampons! But you need to think of it as a long-term investment. A period swimsuit, just like period underwear, is a washable and reusable protection you can use for many years (on average five).

Also, keep an eye out for promo codes, sales, vouchers and other ongoing special offers. Packs or custom bundles are also a great deal. Putting together personalised sets lets you build an effective, tailored period routine.

Even if it feels like a significant amount to pay upfront, it’s a real investment for the months and years ahead.

Good to know: at Louloucup, the bigger your bundle, the cheaper each swimsuit becomes! For 5 items in your pack, each item comes to €22.90 instead of €28.90. A quick reminder of prices before discounts from custom bundles, sales and promo codes: 

The Manon bikini bottom in XXS comes at a mini price of €22.90 (it’s eligible for the sliding-scale custom bundle!)

All the other Louloucup swimsuit styles (Juliette, Noa, Laura) are €28.90!

Origin of the swimsuit and composition

Pay close attention to the swimsuit’s composition, the fabrics used, and also its country of manufacture. Take note of the brand’s commitments and values. Made in France, made in Europe? Patented fabrics? Fabrics harmful to health or the environment?

At Louloucup, all our products are certified Oeko-Tex Standard 100. A real quality guarantee!

Reviews from previous customers

To make a thorough comparison, it’s important to read users’ reviews.
Compare comments and feedback—they’re valuable and can really influence your choice. How does the swimsuit fit? Is it comfortable to wear? Is delivery fast? Are users satisfied with the quality?

I was very reluctant at first and quite anxious about trying it. In the end, I’m thrilled with my purchase. Very practical and comfortable. I was able to enjoy going in the water without any worries and had no issues at all. I recommend it! Lucie G., user of the Manon swimsuit.

Swimsuit received quickly. Bought for my daughter. Matches the description. Effectiveness: GOOD and reassuring for teens! Hesitating between 2 sizes, I went for the larger one, but it’s slightly too big and therefore VERY high-cut at the front! Delphine B. bought the Manon style.

For your info, here are the ratings of our Louloucup swimsuits in January 2026: 

Manon is rated 4.5 / 5 ⭐️

Laura is rated 4.62 / 5 ⭐️

Juliette is rated 4.38 / 5 ⭐️

Noa is rated 4.73 / 5 ⭐️

Menstrual flow

Another key factor when choosing your period swimsuit: your flow. Light, medium, heavy or hemorrhagic – make sure you know the different absorption capacities of your bikini. This is crucial to avoid any unpleasant surprises.

The model, the aesthetics of the swimsuit

Finally, and of course, the choice of menstrual swimsuit will also depend on the teen’s tastes. Plain, black, simple, with flair, bright, colorful, simple bikini bottoms or a one-piece menstrual swimsuit? The choice is wide. Brands adapt by offering fun and pretty models that are easy to wear.


  • A one-piece period swimsuit is full-coverage and classic. It has the advantage of hiding a slightly bloated tummy during your period. You can also wear it as a bodysuit with a sarong at the beach, for example. It’s very easy to wear and goes completely unnoticed.

  • The period bikini bottom is another possible solution. You can pair it with any bikini top you already own for a cool, mix-and-match look. Period bikini bottoms look just like any regular swimsuit bottom.

No one will guess you’re on your period. This swimsuit style is very discreet and very thin. It doesn’t puff up.

All our period swimsuits are available from size XS.

🩱 In short: teen period swimsuit comparison

In France, many menstrual panty brands offer one-piece or two-piece menstrual swimsuits, so you have plenty of choices. The ranges of menstrual swimsuits for teenagers target a young audience with trendy colors, styles, and patterns.
