Gustave Tassell (February 4, 1926 – June 9, 2014) was an American fashion designer and Coty Award winner who became a fashion star in the early 1960s with starkly refined clothes that appealed to women like Jacqueline Kennedy Onassis, Greer Garson and Princess Grace of Monaco. Tassell (pronounced Tass-SELL) designed clothes that Jackie Kennedy wore as first lady on a highly publicized goodwill tour of India in 1962. That year the fashion press hailed him as one of America's hottest new designers.
