High-waisted briefs

Like a corset, these shapers cinch in at the belly to carve out an hourglass. One we like: Spanx Higher Power Panties ($38, Spanx.com). Thanks to a blend of firm yet breathable nylon and spandex, Spanx suck in any flab, painfree. Plus, a silicone waistband prevents roll-down so the shaper stays put all night.
