Hubert De Givenchy is a French aristocrat and fashion designer. Having been impressed by the 1937 World's Fair in Paris, Givenchy decided he wanted to work in fashion, and founded the House of Givenchy in 1952. At only 25 he was the youngest designer on the progressive fashion scene in Paris, seeking to distinguish himself by innovation, in contrast to the more conservative designs of other contemporary designers. Givenchy has had clients as varied as Jacqueline Kennedy and Audrey Hepburn, whose professional and personal wardrobe was largely designed by him.
