By laying each sequin flat and side by side it allows the light to catch the fabric in the most wonderful of ways

From his first film in 1941 he was responsible for many of the best looks on film, dressing stars like Rita Hayworth, Gene Tierney (who he married), Audrey Hepburn, Marilyn Monroe, Lana Turner and the list goes on and on. In 1952, he opened his own fashion house on Seventh Avenue. By 1961 he was appointed by Jacqueline Kennedy as her exclusive couturier.
