Redefine your waistline! Inventor Sara Blakely, tired of panty lines and hard-to-wear underwear, took a basic idea–comfy undies that slim your figure–and turned it into a million dollar enterprise. Her line of Power Panties and footless leggings feel great and get your body red-carpet ready. It’s no wonder they’re a Hollywood favorite. Oprah, Gwyneth Paltrow, Gwen Stefani, and Renée Zellweger, are just a few of the A-listers that enjoy regular Spanx-ing.
