Spanx, Inc. is an American intimate apparel company with pants and leggings, founded in Atlanta, Georgia, United States (U.S.). The company manufactures mainly pantyhose and other undergarments for women and, since 2010, produces male garments. Spanx specializes in foundation garments, including undergarments and bodysuit shapewear, which are intended to give the wearer a slim and shapely appearance.
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 the age of 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. Blakely's 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 also inserted into the waistband. For her product development, Blakely created different waistbands to suit different-sized consumers.
