Susannah says sweatpants, sweatshirts and elastic waists always add pounds. And Michelle was tucking in her tops, accentuating her worst area, her tummy. "By putting her in this, we're skimming over the tummy, which is the little, dodgy, flabby bit that does still exist but you can't see it," says Susanah. "Also, you carry some weight on your leg. With the one-tone jean we slim down the leg. And we have this curtain effect [with the top], cutting the leg in half, making you look 20 pounds lighter."
