Plus-size period underwear: the benefits
✅ Unmatched comfort and newfound freedom
Louloucup’s plus-size period panties fit all body types, including curvier figures, thanks to their size range from 2XL to 5XL. Their ergonomic design hugs your curves for comfort that’s unmatched by traditional products. What makes our models so comfortable?
Made with breathable fabrics like organic cotton, they eliminate any feeling of dampness and unpleasant odors. Cotton provides both breathability and softness—a real plus. Know that all our models, without exception, are lined with organic cotton. This way, your intimate areas are always in contact with this natural material, free from pesticides or harmful chemicals.
We’ve completely redesigned the cuts and reworked each style so they fit just right. We’ve added more fabric and refined the lines so the underwear won’t itch.
These period panties have a wide absorbent panel sewn into the core of the underwear. This means you’re free. Free to go wherever you want, free to exercise, free to sleep soundly.
Thanks to their precise fit, these panties offer total discretion under clothing, even tight outfits.
Plus-size period underwear lets you feel completely at ease, allowing you to forget about your period for up to 10 hours thanks to absorption equivalent to up to 5 tampons.
✅ A healthy, eco-friendly, and cost-effective solution
Louloucup plus-size menstrual panties are certified free of harmful substances (OEKO-TEX® STANDARD 100 and GOTS labels). Unlike disposable period products, they avoid exposure to potentially irritating chemicals and reduce the risk of toxic shock syndrome.
Louloucup period underwear is designed to protect your privacy. The inner layer is made of GOTS-certified organic cotton, while the outer layers of nylon and elastane ensure softness and breathability. The OEKO-TEX® certification guarantees there are no harmful substances, such as PFAS or silver nanoparticles, for safe use.
From an environmental perspective, one pair of period underwear can replace 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.
Economically, each Louloucup underwear costs €28.90 apiece. If you add several styles to your cart (which we recommend for a stress-free, smooth period routine), you’ll save on every menstrual product. Example: 3 plus-size menstrual panties in your cart come to €25.90 each instead of €28.90. With Louloucup, it’s simple: the more you buy, the more you save. It’s a bundle with a sliding scale price. The price per item drops. 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 use a promo code for even more savings! Over 3 years, that’s an average savings of €235 compared to traditional period products. In short, menstrual lingerie is a purchase that quickly pays for itself! 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 to class, on the go, at work, while traveling, or at home. During sports, day or night. It lasts for hours without leaking.
⚠️ We can’t stress this enough: to avoid unexpected leaks, you need to choose a model that’s sized and suited to your period and your menstrual flow. If you use a copper IUD, we recommend opting for models designed for very heavy flow. If your periods are light, short, and not very intense, medium flow models will be enough. It’s important to know your body well before ordering your plus-size period underwear!

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