    Comfy and oh so smooth

    I’m really loving my new bikini panties! So far they are extremely comfortable and don’t give me a wedgie! I love the bikini fit and that does include not covering your butt cheek entirely but that is fine for me! Love the multiple colors in this pack as well!

    Gusset color not as advertised

    These are my go-tos and I keep well stocked. Annoying issue with recent order though: I specifically chose a color because the website photo showed black gussets with them. I hate the skin-color gussets. Received my order, and the underwear I ordered were there, but skin colored gussets instead of black! This was literally the exact thing I was trying to avoid. Knix, how can I be sure to get the gusset material I want next time?

    Why would a period underwear company sell regular underwear without any kind of absorbency.

    Love them

    After trying a few different styles, I have settled on these as my favorite. Will keep buying these and light leakproof as needed. Would recommend to anyone because many styles are available
