    Cute but leak

    The panties are beautiful, comfortable, A1 customer service, but they are not leakproof. For super sleepover panties, after 1 hour on my day 1 (I was wearing them in the day driving), I was completely stained which stained what I was wearing over them. I managed to remove the stains from the panties and short by washing them immediately, but I don't know if it would have gone away if I hadn't been able to wash them right away (like after a full night). Still disappointed for the price and the fact that I bought several pairs! You have to wear the menstrual cup as well, for days 1-2-3 in my case. I was searching for something to feel confident and free, but that’s no the case unfortunately!

    I like the fit so use these daily. Never had leak during my period. I do change several times a day and during the night just my preference.

    Ma fille les porte même en journée

    Très confortable. Ma fille était soulagée d’avoir ce genre de sous-vêtements et de ne pas avoir à gérer des serviettes hygiéniques.
