Stays on in pool.

Wicked comfortable and the sassy slit to the side doesn't hurt either. There is a silicone strip inside the waistband that really helps keep the skirt in place and not rolling down my belly like a cinnamon roll.

They should make these with the "back" a smidge longer for "women" with a nice backside... This wasn't made to fit our type! It's not long enough.

I tried on many swim bottoms this season. This one was average. The waistband was narrow. For hourglass and pear, a wide waistband is a better choice to define shape and take eyes away from hips and thighs and set eyes on a narrower waist. However, an apple might find the narrow waistband more comfortable and less confining. I am a thickening (middle aged) hourglass. This skirt just sort of hung on me. Maybe an apple or straight/athletic build would appreciate the cut more. I did not note any tummy control. The skirt was very comfortable though not particularly flattering on me. (Then again, it wasn't unflattering, either.) Your mileage may vary.
