Quit doubling up on sports bras! If you've got an ample chest, stick with a sports bra with cups rather than the "uniboob" options that dominate the market. With its wide, padded straps; firm underband; and molded cups, the Panache underwire sports bra ($68; panache-lingerie.com) will keep your girls in check even during high-impact workouts. A less expensive alternative: Marika Miracles at Cacique (Lane Bryant's lingerie line).
