The story of SPANX starts with a pair of unforgiving white pants and some serious ingenuity. Before leaving the house one day, SPANX founder Sara Blakely was looking for a smoother - fitting waistbands, so the then salewoman snipped the legs off some control - top pantyhose - and unknowingly laid the foundation for the SPANX shapewear line. Some product development and a handful of celebrity clients and media endorsements later, SPANX leggings, tights, and other shapewear have become a must-have addition to the underwear drawers of women around the world.
