it rolls up. Returned it. I don't know what you can do to improve it...I I couldn't wear it so back in went..

I thought this would pull my stomach in more. I still see a little bump when I wear this item.

Easy to manage, no bra straps, no underwear like fit, just slide on -covers entire waist area from very bottom of stomach bikini area to all way up to bra... Good fit and I'm glad I purchase may order the black color. Buy you will not regret, I wear a 14 and ordered a large fits perfect, very comfortable I pull mine up from legs but I guess you can overhead this is just the way that was better for me. Fits snug but comfort.

Bought for a smaller framed woman, and it just sat on waist, no slimming, but laid as if a "camisole" w/o straps. May work better in larger sizes but did nothing for size 2 whose hope in purchasing was the more hourglass figure it should have given.
