Spanx, Inc. is an American underwear maker focusing on shaping briefs and leggings, founded in Atlanta, Georgia. The company manufactures mainly pantyhose and other underwear for women and, since 2010, produces male underwear as well. Spanx specializes in foundation garments intended to make people look thinner than they actually are. Following her graduation from Florida State University (FSU), Walt Disney World Resort employee Sara Blakely joined local stationery company Danka to sell fax machines door-to-door. In the heat and humidity of Florida, she tried unsuccessfully to find pantyhose that didn't have seamed toes and that didn't roll up the leg after she cut them. Investing her life-savings of $5,000, she moved to Atlanta at age 27, where she researched and developed a hosiery concept predominantly on her own. The creation of the initial product prototype was completed over the course of a year and involved Blakely, her mother, and her friends personally testing the garments. This was innovative at the time, as the industry did not test products with people. Blakelys research revealed that the industry had previously been using the same size waistband for all hosiery products to cut costs, and a rubber cord was inserted into the waistband. For her product development, Blakely created different waistbands to suit different-sized consumers.
