Dress 10 Pounds Slimmer!

After: A Sleek Sheath

Better off red! This dress (Ergofit by Rafaella, $109) provides enough structure so curvy women like Etheliya can go bright (for traditionalists, it also comes in black). Its hidden asset: a mega-stretchy lining that subtracts inches. "It makes me feel sexy and elegant," says Etheliya, 27, a restaurant wine consultant. Skin-tone shoes (Giuseppe Zanotti Design) elongate the look of her legs. Earrings, Anna Ruth Henriques. Bracelets, CC Skye and Lia Sophia.
 
Tip: A body-shaping mesh lining means guaranteed smoothness.
