I purchase the recommended size for my measurements, however the fit is too large at the top so i expect it will come down in use, as its not free to return i will just have to make do. The visable line for the skirt part shows through the tankini top which is unappealing. Also the description states it provides 'control' which please do not expect miracle, i found it does not feel firm to my skin as expected when you purchase control underwear for example, perhaps this is because i should have had smaller size. It does not make me feel smoother and my stomach flatter, in fact the visable seams and lack of control combined with the pants underneath actually make me look very lumpy. ( i am slim build) the only benefit for me with this skirt is that i struggle to find tankini that doesnt flash my stomach, and this clearly prevents that from happening. I would recommend ordering a size down from what this site tells you to.
