Before: "It's hard to find sexy support," Vivienne admits. In the back, this bra rides up and makes her look fleshy; in the front, she needs "a deeper, less rigid cup so she won't pop out," says Susan Nethero, president of Intimacy, a bra-fitting business with stores in Atlanta and New York City. "In a T-shirt, she'd seem to have two sets of breasts—the 'double bust' effect."
After: Vivienne went from a 32C to 32DD for better coverage and greater stability ("I can walk without jiggling!"). This "balcony" style, midway between a demi and a full cup, is both cute and practical: "The fine lace and silky texture make me feel flirtatious."
