Thick waist?

Try a belted romper

Thanks to an elasticized belt that cinches the waist and carves out curves, a structured romper not only conceals a thickerlooking middle, it optically minimizes it too. What also helps: A romper with a deep V-neck acts like an arrow pointing in and down, creating the illusion of a tiny waist, while one with thigh-skimming, flared-hem shorts directs attention away from the middle and toward gorgeous gams instead.
