Reliable, pretty, comfortable, healthy intimate lingerie available in size 44 and up (XXL)? That’s very good news.

Because all women should have access to washable, durable, and effective period protection, Louloucup, a French brand of menstrual products, offers period panties in sizes 44, 46, 48, 50 and beyond.

So that no body shape is left out, we say a big yes to the XXL period panty, triple XL, quadruple XL, or 5XL! Discover the Louloucup range without delay: a collection of plus-size period panties for very heavy flow, heavy flow, and normal menstrual flow.

XXL and up period underwear: an obvious choice! 🫶🏽

Period underwear should be accessible to as many teenagers and women as possible. Beyond standard sizes, period panties must be available in size 44 and above! So what can you expect from this type of washable, reusable period protection?

Real comfort. Well-designed, high-quality period underwear stands out for its comfort and softness. It offers a truly pleasant wearing experience. The materials and fabrics used in its composition feel good on the skin. You can breathe. You feel good in it. No bad odours, no damp feeling. In terms of finishing, at the hips or the groin, the underwear doesn’t “cut into” the skin, doesn’t irritate, doesn’t leave marks. Period panties or a plus-size period brief must be a comfortable, soft, pleasant form of period protection, far ahead of internal products (tampons) that irritate, or pads that move around or stick uncomfortably.

Plenty of style and femininity. XXL or larger period underwear should still be beautiful lingerie above all! Lace, pretty prints, colours, high waists, finishes, embroidery, dotted mesh – in a plus-size period panty, you feel good, pretty, confident, feminine and… sexy! The different shapes and styles (shorty, high-waisted, boxer, thong, bloomer) must rise to the challenge of absorbing bleeding while flattering the body and its curves. Having your period and feeling sexy? It’s possible!

Strong absorption and leak-proofing. XXL or plus-size period underwear must have sufficient absorption capacity (from medium to very heavy flow) while remaining absolutely discreet. The absorbent gusset at the core of the underwear has truly exceptional absorption capacity despite being thin, and the final fabric layer blocks any fluid trying to escape. The result: the XXL period underwear stays in place all day or all night (ideally 8 to 10 hours) without saturating, overflowing or leaking. You can relax, get on with your day without worrying, or sleep without fearing stains on your sheets and pyjamas.

“Period underwear must be suitable for all body types, all curves, all shapes, all sizes, all bodies.”

We’re all obsessed with the Clara high-waisted plus-size period panty! 😍


  • No doubt about it: this is our most beautiful pair of period panties!

  • And like all products on the Louloucup shop, Clara is eligible for the custom sliding-scale bundle! The more items you add to your cart, the more the unit price of each item goes down!

All about Louloucup XXL period underwear 👑

Well-cut lingerie

So, promoting the image of an inclusive brand is great! But what does that actually look like in practice? Because our users, and us too, are tired of:

  • ENOUGH of badly cut period underwear that “won’t stay up” and gapes everywhere!
  • ENOUGH of XXL period underwear that doesn’t respect your curves and digs into your skin! 
  • ENOUGH of super uncomfortable period underwear!

One of the main qualities of period underwear is its design. To be effective, it has to be well designed, well cut, well sized and well made. This quality is even more crucial when we’re talking about underwear in double XL, triple XL or quadruple XL. Underwear must respect the body and adapt to it, not the other way around.


The Louloucup plus-size range has been completely rethought and redesigned to hug the body’s beautiful curves. Extra fabric has been added in the right places compared with the original styles so they always “fit just right”.


Well cut and well sized, our XXL & up period underwear doesn’t dig in, pinch or leave marks on the skin. The elastics don’t cut into the skin at the hips or the crotch. Wearing them feels pleasant and comfortable. In short, everything is designed so you feel genuinely good in our period panties.


Premium-quality period underwear

“Okay, your period panties are available in XXL, XXXL and even 5XL! That’s great, but we don’t want to buy just anything either! We want compositions that respect our bodies and the environment, traceability, guarantees, labels! In short, we want sizes AND quality!” 


Louloucup makes no compromises on the quality of its products. We are committed to offering our customers period panties that are as pretty as they are healthy.



We can be proud to present clean panties, organic, vegan, with a limited carbon footprint. Our fabrics and panties are regularly tested in independent laboratories. We guarantee XXL period panties free of silver nanoparticles and harmful or toxic chemicals.



Furthermore, we remind you that all our panties are lined with organic cotton. This way, your intimate area is always in contact with a natural, healthy, non-toxic material. With a clean composition, you reduce allergies, reactions, and irritations, while preserving and respecting your skin, your body, and your intimacy.

All our styles are certified Oeko-Tex Standard 100, a true mark of quality!

All our products are PFAS-free, free from endocrine disruptors and free from pesticides.

The cotton used inside all our panties is GOTS certified.

Finally, all our products are vegan (no animal-derived materials) and cruelty-free.

Record absorption, reliability you can truly count on!

Having plus-size period underwear is great. Having XXL period underwear that’s even more absorbent and reliable is even better! Louloucup guarantees the same absorption performance as with its other period panty styles.

Our styles available from XXL to 5XL are all highly reliable and very effective at holding and trapping period blood and, for some models, also light urinary leaks. The absorbent gusset sewn into the period underwear is wide and extends well to the front and back of the panty.

Our XXL period underwear guarantees long hours of dry protection with no damp feeling and no bad odours. If you choose the right model for your flow, you can feel at ease for a full day without worrying about saturation.

Far better than leaky tampons or scratchy disposable pads, the XXL organic cotton period underwear is soft, comfortable and super absorbent.

Period lingerie that deserves proper care

Whether your flow is normal or heavy, whether you wear XXL or 5XL, it’s important to take good care of your period underwear so you can use it for a long time! Proper care really does extend its lifespan and how long you can use it. Feel free to check out all our care, cleaning and washing tips on our blog under the Care tab. But let’s already recap what you need to do to wash your XXL period underwear the right way: 


  • Rinse it in cold water as soon as you’re done wearing it to flush out as much flow as possible from the absorbent layer.
  • Then wash it in the machine or by hand in lukewarm water at 30°C with a gentle, non-greasy detergent.
  • Air-dry it away from direct heat sources and never use a tumble dryer!

Depending on how thick the style is, drying can take a little while. So it’s smart to always have one or two clean, ready-to-wear period panties on hand so you’re never caught off guard! 😉
