Here’s the ultimate guide to finding the best period underwear for teens and having a worry-free period!

🪷 Best period panties for teens: how to choose?

Disposable pads, tampons, menstrual discs, menstrual cups (or period cups), washable cloth pads—teens have plenty of options to manage their periods!


Disposable single-use protection, internal protection, washable protection, absorbent fabric protection—today, teens have options and that’s a good thing. So, why choose period underwear, and how do you find the best period underwear for teens?


  • Easy to use. Unlike disposable products, period underwear is worn just like regular underwear. It’s that simple. You almost forget you’re on your period.

  • Guaranteed discretion. Even though period underwear is very absorbent and can hold a lot, it doesn’t swell or show through. It stays very discreet or even invisible under clothing. Some models are even seamless so you can wear them completely unnoticed.

  • A healthy and eco-friendly alternative. By choosing period underwear, you’re opting for a washable, durable, reusable menstrual product that’s more environmentally friendly. Period panties produce zero waste. They can be washed and reused for many years.

  • Comfort and confidence. Well-designed, well-fitted, and thoughtfully made, period panties provide excellent support and absorb all flows efficiently, letting you experience your period stress-free!

Best Louloucup period panties for teens: our picks

🪷 How do you choose the best period underwear for teens?

Before you buy one or more pairs of menstrual underwear, there are several criteria to consider to make the best choice for a teen. What are they?

❀ The absorption level of the period underwear

Period underwear comes in several levels of absorbency:

  • Light menstrual flow. For those with a lighter period.

  • Medium or normal menstrual flow. Perfect for regular, moderate flow.

  • Heavy to very heavy menstrual flow. Designed to effectively handle significant bleeding, especially if you have a copper IUD or are in the postpartum period.

For example, Louloucup’s Mathilde very heavy-flow period panty is specially designed to handle very heavy or hemorrhagic flow. Its absorbency is equivalent to five tampons, making it an ideal choice for days with heavy bleeding. The wearer stays dry. No “stewing” effect, no dampness—the wearing experience is very comfortable. Interested in this kind of style? Check out Louloucup’s full heavy-flow period panty collection!

❀ The size, cut, and style of your period underwear

Fit is essential for teens. It’s crucial to choose underwear that hugs their shape perfectly to provide optimal support and maximum comfort.


  • Size guide. Every brand has its own size guide. At Louloucup, the Mathilde period underwear is available from XXS to XXXL, and the Lucie style comes in sizes from XXS (teen version, equivalent to a size 34) up to XXL.

  • Tailored fit. A higher waist, like Mathilde’s, offers a comforting, enveloping effect, while Lucie’s cut with flat seams guarantees invisibility under tight clothing. Each style has great features! 

❀ Fabrics and materials used

The quality of materials and fabrics directly affects the comfort and effectiveness of period underwear. Here are some things to check:


  • Organic cotton is the ideal natural material. Certified organic cotton feels soft and reduces the risk of irritation. Organic cotton is a must-have for period underwear!

  • Polyamide makes the underwear durable and gives it the stretch it needs, while also making it easy to care for.

  • The absorbent fabric sewn into the core of the underwear is dense and thick. The absorbent area should stay discreet while offering excellent retention.

❀ Design and aesthetics

Teen girls want to wear underwear that reflects who they are. That’s why design plays an important role:


  • Careful finishing touches. The Lucie underwear, for example, features a subtle finish with gold details for a feminine, elegant touch.

  • Variety of colors. Some panties, like Mathilde, are available in several colors (the Mathilde model in black for very heavy flow, and the Lily model in blue for medium flow) to suit everyone’s tastes.

❀ The final personalized tips from Louloucup

To choose the best period underwear for teens, here are our three Loulou tips:


  1. Choosing your size. It’s important to check the brand’s size guide, and if you’re unsure, don’t hesitate to go up a size for extra comfort.
  2. Care. Regularly wash your underwear in cold water, avoid harsh detergents and fabric softeners, and do not tumble dry your menstrual lingerie to preserve the quality of the absorbent fabrics.

  3. Try several models. Every body is different. It can be helpful to try out different styles to find the one that offers the best fit and optimal comfort right from the start.
