Born in Noblesville, Indiana, Norell arrived in New York City in 1919, studied fashion illustration and fashion design at Parsons School of Design and Pratt Institute, and began his career designing costumes for silent-film stars. Before partnering with Anthony Traina to form the Train-Norell fashion house in 1941, Norell spent twelve years with Hattie Carnegie as a designer for her custom-order house. In the 1960s Norell became the sole owner of his own fashion house on Seventh Avenue in Manhattan. Norell amassed numerous private clients, including Hollywood stars and entertainers, wealthy socialites, and the wives of politicians and industrialists. On occasion, Norell created fashion designs for Hollywood films. Norell considered his greatest contribution to fashion was the inclusion of simple, no-neckline dresses.
