Known for designing the little black dress that Audrey Hepburn wears in the opening scene of 1961's Breakfast At Tiffany's, Givenchy was a trailblazer in the world of ready-to-wear fashion.

Born into an aristocratic family in the northern French town of Beauvais, Givenchy was a physically towering man who launched his first collection to immediate fanfare, as Reuters reports:
