With Louloucup, you’re choosing a zero‑waste, inclusive solution. One single panty is all you need to get through your period with no hassle and total peace of mind, whatever your body type.

Plus-size period panties: the benefits

✅ Unmatched comfort and a newfound sense of freedom

Louloucup plus-size period panties adapt to all body types, including curvy figures, thanks to the extended size range from 2XL to 5XL. Their ergonomic design hugs your curves for comfort that can’t compare with traditional protection. So what makes our styles truly comfortable?

Designed with breathable fabrics like organic cotton, they eliminate that damp feeling and unpleasant odours. Cotton is both breathable and soft, which is a real plus. Know that all our styles, without exception, are lined with organic cotton. That way, your intimate area is always in contact with this natural material, free from pesticides or harmful chemicals.

We completely redesigned the cuts and reworked every style so that they fit just right. We added more fabric and adjusted the lines so the panties don’t itch.

These period underwear feature a wide absorbent panel sewn into the core of the panty. That way, you’re free. Free to go wherever you want, free to work out, free to sleep soundly.

Thanks to their precise fit, these panties are completely invisible under clothing, even tight-fitting outfits.

Plus-size period panties help you regain total peace of mind, letting you forget about your period for up to 10 hours thanks to an absorption capacity equivalent to 5 tampons.

✅ A healthy, eco‑friendly and economical solution

Louloucup plus-size period panties are certified free from harmful substances (OEKO-TEX® STANDARD 100 and GOTS labels). Unlike disposable period products, they avoid exposure to potentially irritating chemicals while reducing the risk of toxic shock syndrome.


Louloucup period panties are designed to protect your intimate area. The inside is made from GOTS-certified organic cotton, while the outer fabrics in nylon and elastane ensure softness and breathability. The OEKO-TEX® certification guarantees the absence of harmful substances such as PFAS or silver nanoparticles, for safe use.


From an environmental standpoint, a single panty replaces up to 2,500 disposable products over 5 years. With simple care (rinse in cold water, machine wash at 30°C, air dry), they last 5 to 7 years, preventing tons of non-recyclable waste.


Financially, each Louloucup panty costs €28.90. If you add several styles to your cart (which we recommend so you can enjoy a calm, low-stress period routine), you save on each menstrual product. Example: 3 plus-size period panties in your cart come to €25.90 each instead of €28.90. At Louloucup, it’s simple: the more you buy, the more you save. It’s a sliding-scale bundle price. The price of each item goes down. With 5 products of your choice in your cart, you save over €30! Plus, shipping is free. And before you check out, don’t forget to add a promo code to save even more! Over 3 years, that’s an average saving of €235 compared with conventional period products. In short, menstrual underwear is an investment that pays for itself very quickly! And the freedom it gives you is truly priceless!

✅ Reliable, effective and safe protection

With plus-size period underwear, there’s no room for doubt. You can wear it in class, on the go, at work, while traveling or at home. During sports, at night or during the day. It lasts for hours without reaching saturation.


⚠️ We can’t say it enough: to avoid annoying leaks, you must choose a style sized and adapted to your period and your **menstrual flow**. If you have a **copper IUD**, we recommend opting for very heavy-flow styles. If your periods are quite light, short, and not very intense, medium-flow styles will be enough. It’s important to know your body well before ordering your **plus-size period panties**!

How do you choose the right plus‑size period panties?

Finding the perfect size: the secret to flawless effectiveness

A well-fitted size guarantees comfort, effectiveness and security. In menstrual lingerie, good absorption depends on a snug fit. Your washable period panties need to sit correctly so that your flow is absorbed as efficiently as possible.


Louloucup offers period briefs from 2XL to 5XL, or sizes 42 to 50. For the best fit, measure your waist and hips, then refer to the chart below:

Louloucup sizing
Waist measurement (cm)
Hip measurement (cm)
2XL 90–98 114–122
3XL 99–107 123–131
4XL 108–116 132-140
5XL 117–125 141–149

Did you know? Our plus-size period panties Clara, Fanny and Liv are available up to 5XL, so treat yourself! These are our most effective products for very heavy periods. The high absorbent area at the front and back boosts protection at night or during intense flow.

Match absorbency to your menstrual flow

Every menstrual cycle is different. Don’t compare yourself. Your periods, their nature and intensity, change over the course of your life. To anticipate and enjoy a more harmonious cycle, choose a varied range of washable period underwear with different absorbency levels.

Light to medium flow: Styles like Ella, Gaby or Margot are ideal for medium flow, or for the beginning or end of your period. Black, thin, feminine, discreet and soft, these are absolute must‑haves!

Heavy flow: Fanny and Leo offer a capacity of 4 to 5 tampons. Perfect for intense days.

Very heavy flow or night: Clara, Mathilde, Liv or Jade are powerful allies for anyone with intense periods. Their wide, high absorbent area ensures maximum security, even when lying down.

For nights or post-partum, Clara or Jade, with their double thickness, prevent stains on your sheets.


For complete invisibility, go for Liv or Gaby, which are totally seamless!


Do you love lace and polka‑dot mesh? Magot with its pretty waistband, Ella with its sheer details or Clara with its couture touches are sure to win you over!


Customer reviews (Clara 4.8/5, Liv 4.9/5) highlight how effective and comfortable they are, even for sporty users or restless nights.

“By choosing lingerie that makes you feel amazing, you can turn your period into self-care.”

Bonus: washing plus-size period underwear

Plus-size period underwear, like those in the Louloucup range, only require simple care to maintain their effectiveness and lifespan. Did you know that a few basic habits are enough to keep them performing well for years?

The care guide to keep them effective for as long as possible

To keep your Louloucup plus-size period panties as effective as on day one, follow these clear steps:

Rinsing: After use, rinse immediately in cold water until the water runs clear. This prevents stains and preserves the absorbent fibers.

Washing: Machine-wash at 30°C in a laundry bag. Avoid fabric softener and Marseille soap, which clog the fabrics.

Drying: Air-dry only, without using a tumble dryer or any direct heat source. This preserves the waterproof fabric and extends the product’s lifespan.

How many plus-size period panties do you need for your period?

The ideal number varies depending on how heavy your flow is and your habits. On average, 3 to 5 pairs of period panties allow for a comfortable rotation. For a heavy flow, opt for 5 to 6 pairs. Our custom bundle with sliding-scale prices lets you stock up and save money—keep it in mind!
