Go buy a pair of Spanx to wear under the other shaper -- you will be so shaped, you probably won't be able to breathe, but the Spanx will tame the tummy, and the outer shaper should make the line from the top of the Spanx disappear. If you are worried take dress and shaper with you to try on the Spanx. Get the high kind of Spanx, by the way, not the kind that comes to your waist--the kind that comes to under your breasts. Or, maybe even better, try to find the kind of shaper that looks like a bodysuit with shorts attached. Some sites call them Singlets-- they cannot ride up. THey are, however, hard to find. I bought mine at Nordstrom I think. The regular bodysuits that do not go down the thigh (They look like one piece bathing suits) I do not like because of the top of the thigh bulge thing going on.
