    Not a fan

    Sadly these are just way too big for me to even judge... I was so uncomfortable in them. So sad as I was so excited.

    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!
