A fashion icon for the ages, the late Oscar winner was unapologetically herself, with a penchant for menswear staples, belted waists, brimmed hats, turtlenecks, chunky ankle boots and a strict black-and-white color palette.
Meryl Streep honored Keaton at the 2017 American Film Institute Lifetime Achievement Awards, describing her friend as “arguably the most covered-up person in the history of clothes” yet “transparent” when it comes to her personality and performances.
Keaton never employed a stylist, instead approaching everything — from a dog walk around Brentwood, Calif., to an awards show red carpet — with the same sartorial point of view.

The actress was one of the few whose personal style managed to inform her onscreen personas. And considering Woody Allen famously asked her to dress herself for “Annie Hall,” that comes as no surprise.
From Hall’s borrowed-from-the-boys styling to Erica Barry’s turtlenecks in “Something’s Gotta Give” to Sybil Stone’s full, belted skirts in “The Family Stone,” the closets of Keaton and her characters morphed into one.
Though impossible to encapsulate the legend’s iconic style in a single slideshow, scroll through some of Diane Keaton’s most beloved looks below.
