The menstrual slip No. 1 in France

Our history

Hello, it's me, Stephanie!

Woman, mother, entrepreneur, and advocate for sustainable consumption, I always pay attention to what I buy (to the extent that I spend two hours at Franprix reading the small italic texts on the packaging). But strangely, I didn't think about my menstrual hygiene products for a long time. I had been so conditioned for years that I mechanically bought tampons every month without thinking about it.


But one day I had to help my prepubescent daughter choose a suitable protection and that’s when it clicked. I had to take a step back and educate myself. Then it became clear to me that all these environmentally harmful hygiene products with questionable compositions did not fit my life philosophy at all and were neither particularly practical nor comfortable, especially when it came to managing her first period.


I then became interested in the concept of washable period protection and thought again about the hyper-effective absorbent panties I had already tested after my delivery, which were as ugly and uncomfortable as a giant baby diaper... hello glamour! This is how I came up with the idea of developing a next-generation menstrual panty.

Hello, this is Sisters Republic!

Thus, Sisters Republic was created, a brand for new period protection that is as pretty and comfortable as underwear, while being 100% effective, environmentally friendly, and sustainable..

Since a woman spends a total of 6 years of her life on her period and the period is uncool, we wanted to offer women a feel-good, cheerful, and uncomplicated brand that can finally give them confidence, gentleness, and ease during this not always easy time, so they can smile about everything and feel comfortable all the time, even during their period.

"In short, we wanted to give women the slip that changes menstruation... in every sense of the word!"
