    Good purchase!

    Love the fabric, style, and leakproof absorbency.

    On my first few wearings, I’m finding them tighter than I like. I got size M. Unless they loosen up with use, I’ll order size L next time.

    Ps) I’m 5’3”, 130 lbs.

    Comfortable except for the waistband

    The waistband is way too tight compared to the rest of the panties.

    Always my go-to underwear.

    As someone with Endometriosis, wearing traditional feminine hygiene products is tough, being able to wear period underwear and feel comfortable is important. I like the flow levels they offer. I do find the thin material will allow for the underwear to leak from the sides. Or run over onto the material on the sides. Easy to wash and easy to hang dry. I am 5’5 140 lbs I could wear a medium and probably should but I don’t like tight things on my stomach so I buy a large. If you’re a medium buy a medium.

    Modal Rib French

    Wish there were a little more stretch to them to kind of hold things from jiggling. The legs ride up my butt but not terrible.
