Annie Hall
The actor won the argument.
Ruth Morley is credited, but Diane Keaton wore largely her own thrifted menswear and Woody Allen overruled the designer's objection on set: "Leave her. She's a genius." Ralph Lauren supplied the tie, vest and shirts, yet said the look was "pure Diane Keaton." Keaton credited 1970s SoHo street women as the real designers.
