$1.3 billion: that’s Sara Blakely's net worth. In 2000, Blakely began going door to door with an invisible product. Well, invisible to everyone but the wearer. Spanx was a very different kind of underwear, created to help shape the wearer's body: tucking, hiding, and shaping your body to make you feel better. No longer did you have to go to the gym to get the body you wanted. You could shape your body with your underwear.
If you are as old as me or older, you remember when gym clothes were bulky and formless. Sweatpants and oversized t-shirts were once the expected attire.
