Diane Keaton's clothes were cinema. That much is certainly true when she emerges in Annie Hall after a tennis match in a wide-brimmed hat, khaki pants and an oversize vest with a tie poking out of it - perhaps the most memorable outfit in the history of movies.

That is the moment when Keaton's Annie first connects with Alvy Singer, played by the film's director Woody Allen, and her styling is so immediately idiosyncratic that it tells you everything you need to know about her character: She's unique and a little bit askew in her consummate preppiness, the White Anglo-Saxon Protestant to Allen's nebbish. She looks like no one you've ever seen, a revelation in the tie her "grammy" gave her.
