What should you look for before buying period underwear?
Several factors should be considered to avoid regretting your purchase:
- Menstrual flow. Period underwear is sold according to the level of flow (light, medium, heavy, or very heavy). It’s important to choose your lingerie accordingly. Also, remember that your flow isn’t the same at the start and end of your period. Plan ahead by choosing light flow underwear for the beginning or end of your period, and heavy flow underwear for the middle days.
- Size. Buying period underwear is just like buying regular underwear—you need to pay attention to size. At Louloucup, we make sure to produce underwear according to European standards, from XS up to XXXL. If you’re between sizes, we recommend going with the larger one. You’ll also find detailed sizing advice on each product page.
- A transparent and clean composition. If we avoid tampons and pads made with chlorine and pesticides, it’s because we want to use safe, non-toxic protection! At Louloucup, we make it a point to keep the composition and production of our panties completely transparent. All the fabrics used for our panties are OEKO-TEX certified. Plus, the inside of our panties is made of organic cotton. The vast majority of our production is European. The lace and elastic are made in Spain, the fabrics in Italy, and everything is assembled in Portugal. Finally, our products are regularly tested by independent laboratories.
- The cut is both feminine and comfortable. Today, thanks to period underwear, every woman can finally feel sexy and beautiful during her period! At Louloucup, we’ve worked hard to offer gorgeous panties with harmonious, flattering cuts.
- Price. Period poverty is a real issue. Louloucup has chosen to offer panty packs at very attractive prices to make this hygiene solution as accessible as possible.

At the start or end of your period, for a light flow: the Chloé thong
Made of 95% organic cotton and 5% elastane, the Chloé menstrual thong, made in Portugal, is perfect for light flow days. Black, sexy, but always comfortable, it offers flawless protection for women with lighter, less frequent periods. Its composition keeps you dry all day. This menstrual thong, with its dotted mesh detail, absorbs the equivalent of one to one and a half tampons. It can also be worn during ovulation (discharge) or for spotting. It’s a perfect replacement for disposable pantyliners.
The Chloé thong: sexy, comfortable, and reliable
Once you try it, you’ll love it. Reviews are unanimous about this very feminine underwear. Users praise its effectiveness (no leaks for 12 hours!) while still being sexy. No doubt, you’ll love wearing it!
Discreetly: the seamless Émilie period underwear
Are you looking for invisible period underwear so you can wear your tightest clothes during your period without worry? Our Emilie seamless black medium-flow underwear is perfect. Super comfortable, soft, and cute, you’ll forget you’re even wearing it.
The Émilie seamless underwear: invisible, thin, and comfortable!
Who said you had to give up your favorite bodycon dress during your period? Definitely not with Louloucup! Our customers love how reliable it is while staying super discreet. Some even use it with no worries during their workout sessions. Zero leaks guaranteed!
Vibrant colors with top-notch protection
We wanted to offer both black, understated, and discreet styles (Rebecca model or Naomi) and colorful, lively underwear. For medium or heavy flow, you’ll find a great selection of floral underwear (Léa medium flow), striped underwear (Louise medium flow or Simone heavy flow), or solid underwear (Romy or Lily medium flow). Switch up your colors from day to day and wear our beautiful underwear with pride.
Our little favorite at Loulou? Maybe the Romy model, which is a unanimous hit! Its bright red color, flattering cut, and organic cotton and bamboo fabric have won over so many customers. And us too!
Adolescence, postpartum, perimenopause—underwear for every stage of life
Our washable, absorbent period underwear is designed for all stages of a woman’s life. We even have a collection just for teens. Our underwear is also a valuable ally during other moments of a woman’s intimate life. In the postpartum period, our Loulou heavy flow underwear naturally provides absorption and protection. They also offer welcome comfort during this exhausting and truly overwhelming time!
During perimenopause, hormones fluctuate a lot. Periods can become irregular, lighter, or heavier than usual. The Lily period underwear model, very comfortable and with a high absorbent area, is especially well-suited for this situation.
High-waisted: elegance, protection, and femininity
High-waisted styles are truly on trend. High-waisted period underwear is a must-have for your underwear drawer. Our signature model, Clara, is the most absorbent in our collection. It’s designed especially for women with very heavy or hemorrhagic flow. Extremely comfortable yet feminine, this lingerie piece flatters your body while keeping you protected from leaks. You’ll stay dry thanks to its extra-wide, extended protection that runs from the front to the back of the brief! We wanted a beautiful panty (lace on the sides, satin effect elsewhere) without sacrificing protection. Our users say that even with very heavy periods, they don’t experience any dampness or unpleasant odors. It’s a true ally for anyone with naturally heavy periods or using a copper IUD, for example. The Clara panty can also be worn overnight with no worries about staining your sheets. We love it!
As you can see, day or night, at home, at work, or while working out, under a cute skirt or jeans, Louloucup period underwear can be worn anytime, anywhere. Whether your flow is light, medium, or heavy, from XS to XXXL, we’ve got everyone covered so you can get through this time of the month as smoothly as possible.
We hope this little period underwear comparison has helped clear things up. If you still have doubts, don’t hesitate to contact us with any questions about using the underwear, washing, materials, manufacturing, and more.
