How do you choose the right teen period underwear?

To choose the right teen period underwear, you need to take into account

  • size,
  • the absorption level,
  • and the teenager’s body type.

💖 Size

guide des tailles

A quick note: the chart above doesn’t include the latest sizes we’ve added. For the slimmest teens, we now offer size XXS as well as XXXS, equivalent to ages 10–12 and 12–14.

💖 Absorbency level for your flow

It’s also important to consider the nature of your menstrual flow. Is it light, normal, or heavy? To help you figure it out, we highly recommend this article: How to know your menstrual flow?


We explain, among other things, how to understand your period and talk about flow speed and direction! A must-read if you want to better understand your cycle and your new woman’s body!

Knowing and identifying your flow type will help you choose the underwear styles that suit you best.


Our tip: if you’re hesitating between a medium-flow period panty and a heavy-flow period panty, go for the heavy flow. You’ll be well protected and won’t have to worry about it all day long. 


Another tip: even if you have a heavy flow, don’t forget to add one or two period panties for normal or medium flow. Your period flow isn’t heavy from the first to the last day. For the last days especially, you can easily switch to slightly less absorbent styles, because your menstrual flow tends to slow down.

💖 Body shapes and cuts

Cuts and designs vary a lot—and that’s a good thing! Teens can have fun choosing absorbent period lingerie that’s stylish, cool and gorgeous, and that really matches their taste and vibe!


Shorty, boxer, bloomer or high-waisted panty – at Louloucup you’ve got options! In every case, you’ll find organic cotton and Oeko-Tex Standard 100 certified fabrics (a guarantee of safe products with no harmful or toxic substances). Day or night, you’re equipped to face your period with no risk of leaks.

Louloucup recommends... the Lucie medium-flow teen period panty! 😍


  • Solid black with a small gold trim finish.

  • Ultra-thin and discreet, Lucie features flat seams so it stays invisible under clothing.

  • Ultra soft and very safe, it’s made from 95% GOTS-certified organic cotton.

  • Lucie absorbs the equivalent of 2 to 3 tampons. So it’s a style suited to medium flows.

  • Available from size XXS (teen version, equivalent to a size 34) up to size XXL (equivalent to size 44).

  • Made in Portugal.

  • Price: €22.90 before discount via the custom pack.

Care and durability of teen period underwear


Machine washable at 30°C, teen menstrual underwear needs a pre-rinse in cold water and should be air dried.



To keep your period underwear lasting longer, avoid the dryer and harsh products. Store them in a dry place between cycles. The average lifespan is 5 to 7 years. Check out tips for caring for your underwear and keeping them at their best.

II. What’s in the ideal teen period underwear pack?

For a full cycle, you’ll need 4 to 6 period panties. It’s smart to plan ahead and always have at least one clean pair ready, just in case. 


It’s also smart to mix and match styles to get different levels of absorbency. Period flow isn’t constant, so you’ll want to plan for effective nighttime protection.


With Louloucup, you get two pieces of great news:

first, we offer a teen range. This is a selection of some of our period panties available in sizes 3XS, 2XS, XS and S.

second, we offer the sliding-scale custom pack. This bundle of period products lets you make VERY big savings.

How does it work?

Nothing could be easier! You shop as usual on the Louloucup site. You choose a style, a size and add it to your basket. The more products you add (panties, swimsuits or menstrual cups, anything goes!), the more the price of each item you’ve selected goes down. It’s automatic. You don’t have to do a thing!

What are the benefits of the custom pack?

FAQ – Teen period underwear

What’s the best alternative to tampons for teens?

Menstrual cup and period underwear: teens have options to avoid tampons!
For teenagers, period underwear is an excellent alternative to tampons and pads. It offers comfort and discretion, and is specially designed to meet the needs of young girls, with different absorption levels and sizes available.

Reusable and eco-friendly, it reduces waste while being cost-effective in the long term. Easy to care for, it’s made from healthy fabrics like organic cotton, providing up to 12 hours of leak- and odor-free protection. It’s a hygienic option that lets blood flow naturally, which helps minimize the risk of bacterial growth.

A teen menstrual cup is also an option. This internal, reusable period protection has some great advantages. It does, however, require being comfortable with your body and not being squeamish about the sight of blood. 

Can you get toxic shock syndrome from period underwear?

No! 

Toxic shock syndrome (TSS) is a rare but serious infection caused by the proliferation of the TSST-1 toxin, produced by a strain of Staphylococcus aureus. Unlike tampons and menstrual cups, period underwear allows blood to flow out, significantly reducing the risk of staph bacteria growth.
Washable period underwear is made without fragrances or pesticides, and some are crafted with antibacterial fabrics to ensure perfect hygiene and prevent odors. They’re often made from blends of nylon and elastane—soft, durable, comfortable materials that let your body breathe.

Which teen period underwear is best for very heavy flow?

The teen Mathilde and teen Liv period underwear in size XXS are perfect for very heavy flows!
For a very heavy flow, it’s crucial to choose washable period underwear that offers reinforced protection. Louloucup offers heavy-flow period underwear specifically designed for this need, with triple protection or double absorption for maximum peace of mind.

When choosing, go for styles with a wide coverage area, a broad gusset and soft, breathable materials like organic cotton. Also make sure you pick a size that fits your body shape for optimal comfort.
