    Fit ok to start, but not so great after 8 hours

    Start out ok, but after 7 or 8 hours I found them starting to roll down. Not convenient & awkward trying to adjust.j

    Very Comfortable

    I like that they have a wider crotch than most French cut, and that is better for wearing heavier pads. if you need to.

    I sized up because my waist is larger than iwhen I was young.

    comfortable but not quite high enough

    I have issues with panties rolling down at the top, I think the french cut feels comfy but I feel like I would like them just a tad taller at the waist to keep from rolling

    Like you’re wearing nothing!

    Super lightweight and comfy, no pants lines, and with the French cut no worrying about the leg holes being too tight around the thighs. Highly recommend this style if you have a hard time finding underwear that fits both your legs and waistline.
