With its three-colored rubber waistband, the Frenchy Shorty showcases a preppy chic in French style. Available in two colors: in heather gray or black, it perfectly adapts to all situations with its "French Touch" and ensures coverage against leaks with its shorty cut.
The inner brushed rubber band is very soft on the skin. The elastic certified organic-cotton fabric makes these shorts the ideal menstruation panties for anyone who desires maximum comfort 🍑
This shorty offers up to 12 hours of leak protection, without odor or dampness, so you don't have to change in the middle of the day: practical for school or work!
"Can be used alone if you have a normal to heavy menstrual flow, or in addition to other menstrual hygiene products - e.g. menstrual cup or tampon - on the first day of your period when your bleeding is particularly heavy (hemorrhagic period, endometriosis, etc.)."
Tip: You can also wear your Sisters Republic menstrual shorts during the time you are waiting for your period to avoid unpleasant surprises. The shorts are very thin (less than 3 mm thick), have no "diaper effect" and are invisible under clothing, even under tight-fitting garments, unlike pads. 😉
Available in absorbencies LIGHT for the last days of menstruation, MEDIUM for a light
"for normal menstruation or SUPER for normal to heavy menstruation and for days when"
when your menstrual flow is heaviest or for nighttime.
The materials used to make our briefs are free from harmful substances for the body and the environment (no chemicals and especially no treatment with silver nanoparticles). Our fabrics, lace, and elastic bands are certified organic.
All materials used for production come from the Mediterranean region.

To maximize the absorbency of your period underwear, you should wash it twice before use. To ensure it lasts as long as possible – because Sisters Republic period underwear is washable and reusable for several years – we also recommend:
1/ Rinse the underwear with cold water immediately after taking it off until the water runs clear.
2/ Wash it with the "synthetics" program at 30°C with the rest of your laundry (don't worry, everything will be fine).
We recommend placing your period panties in a laundry bag or in the Sisters Republic 3-in-1 pouch when washing in the machine. Do not use fabric softeners or bleach.
3/ Let air dry and do not use a dryer.
Don't have a washing machine? Use our stain remover soap, which protects the absorbent fabric of our underwear.
I recommend it 100%
"This is the first time I've bought period underwear and I am completely satisfied! For heavy menstrual flow, I used the one with absorbency Super and no leaks (even at night!) I recommend it 100%"
Marine T.
Thank you, Sisters Republic!
"It's a real innovation for all women. You experience your period differently with it, I no longer feel uncomfortable like with tampons or cups. The period panties in the pack have different absorbencies, so you have the right protection for every day."
Camille S.
They are really thin and comfortable
"I have a light blood flow because I take the pill, so for the heaviest day I took a slip with absorbency Medium just to be safe, and for the rest of the time two pieces in "Light." I have the impression that I no longer feel my period because the underwear is so thin and ultra-comfortable. I can wear them all day without worrying, ..."
Annabelle M.
Pleasantly surprised
For someone who only uses tampons, it felt a bit strange at first... I was afraid something would leak, but that doesn't happen. The panties absorb all the fluid very quickly. I'm so glad I don't have to use tampons anymore, especially at the end of my period when it's really uncomfortable!”
Céline R.
It's great
"What is really great is the material, I feel completely comfortable. I chose the strength "Super", even though I have rather average blood flow, but I wanted to be sure that nothing leaks."
Camille.N
Underwear that is now indispensable
"Essential is the adjective that comes to mind when I think of period underwear. The underwear is very comfortable, the blood absorption is good, and above all, you have peace at night. Many thanks for these efficient and comfortable briefs that almost make you forget you have your period!"
Maude.K
I recommend it without hesitation
"It is truly an innovation for all women. I experience my period very differently today..."
Morgane F.

Depending on the length of your cycle, short or long, you will need 4 to 10 panties. If you want to wear your menstrual panties day and night and wash them all at the end of your cycle, you will need between 8 and 10 panties. If you want to wash them to reuse several times during your cycle, 4 to 5 panties will be sufficient. You should count at least one panty for the day and one for the night, multiplied by the number of days your period lasts.

Yes, only size and cut differ. The absorbency is identical – up to 12 hours of protection.
Yes, our teenage panties make periods easier!
They offer freedom of movement and more comfort than traditional hygiene products, with up to 12 hours of protection ✅. For heavy bleeding, they should be changed during the day – just put a second pair of panties in the mini bag!
Don't worry – all our panties, including the teenage models, are free from harmful substances (no chemicals, no silver nanoparticles). The inner layer (the one in contact with the skin) is always made of organic cotton 🌱. No risk of toxic shock like with tampons!
Test our slips under real conditions 😉 for a whole 1 cycle, if you are not convinced, we will refund your money. No questions asked!
