    Run Small

    I am a size medium for the French cut- which I absolutely love- but when I got my 3-pack medium no show bikini underwear they were so tight! They fit too tightly at the waist and cut a strong line across my bum. I ordered them during a sale and am sad I can’t return or exchange for a larger size. The size guide gives the same measurements for all underwear styles so I never expected these to be so tight compared to the French cut style. Size up if you have a booty or wide hips!

    Rolls down belly

    Great colour, good at keeping dry. For women with a more robust figure the bikini cut isn't very comfortable. Rolls down the bikini line. Feel like falling off

    Great appearance but less comfort

    This panties are a bit heavy in the crotch. I love the fit and the fact that the waistband is part of the panty not an add on that doesn't stretch in a different way than the actual panties. I would buy again is menstruating.

    Comfortable

    I was pleasantly surprised by how these underwear felt like regular underwear. The fit seemed true to size, no rolling or gaping. I wish there was a tiny bit more material on the butt. I didn't get a wedgie or have any leaks, I just would've liked a bit more to feel more secure. I also wish that the higher absorbency panties came in a cotton option as I like natural fabric versus synthetic. Still, this was leaps and bounds better than pads. I would buy again.
