    Amazing!

    Incredible. This is my first time trying period underwear. I usually leak through pads and I don’t like using tampons or period cups. I’ve been only using these underwear and the high rise leakproof and I haven’t leaked once. They last so much longer than a pad and are so much more comfortable. 1000% recommend!

    So pretty!

    These are so cute! Never thought I would feel pretty in a pair of period underwear.

    I had to return them for a smaller size however. I ordered Mediums in the high rise and bikini leakproof underwear and the medium in these was huge all over. Definitely size down!

    PLEASE PLEASE PLEASE RESTOCK

    Omg I love these. I haven’t bought period underwear in a while, but I desperately needed new ones and I finally did. I LOVE how these fit and they make me feel significantly less “ugh” during my cycle. I just tried my first pair of these on - got delivered yesterday - and I came right back to buy more but there are severely limited colors/patterns available in my size (medium) - there’s only 2! Please say you’ll restock in other colors/patterns in this style!
