If You're Big-Chested...

"Finding bathing suits is hard because my top half is much bigger than my bottom," says Dawn Zimniak, 29, a residential real estate agent. Zimniak relies on mix-and-match separates, strategically placed embellishments, and occasionally even a tailor. "I shop for suits with structure so I can run around and not worry about a wardrobe malfunction," she says. This patterned minimizer (Miraclesuit, $144) is supportive and slimming; gathered fabric at the waist creates a flattering division between chest and hips.
