Despite their strict diets and dedication to exercise, even the most in-shape celebs rely on body-shaping garments to make their figures look perfect in skin-tight dresses on the red carpet.

Take Sofia Vergara and Halle Berry for example, who often slip on a full body-shape undergarment from Result Wear before stepping out in their slinky styles.

"It's seamless, enhances a woman's figure in all the right places and is quite comfortable!" their stylist, Deborah Waknin, explains to Us Weekly.

Agrees Result Wear creator Kiana Anvaripour, "The Marilyn slip ($169, is the ultimate secret weapon for an hourglass figure."

For those who don't need full coverage, opt for the Stella skirt ($119, to smooth the hips or the Jane bra ($79, for a sexy lift.
