 Although Edith Head (qv) won an Oscar for costume design, most of  Audrey Hepburn (qv)s wardrobe was by Hubert de Givenchy (qv).  In fact, Hepburn chose her own clothes to wear from de Givenchys  collection. This was her first time working with the French  designer, and he would become her costumer of choice for most of her  career.
