Even before all the ties, hats, and high-waisted pants that became synonymous with her wardrobe, Diane Keaton practically arrived on the scene as a style icon with her role in 1977’s Annie Hall. As it turned out, that was just the beginning: She quickly became the queen of menswear with a love of suits that’s now spanned more than four decades (and may still be inspiring ‘fits from the likes of Bella Hadid). The Academy Award winner has adopted other signatures in that time, too: Her red carpet appearances are all but guaranteed to feature either gingham print, piles of pearls, heels with socks, a Babadook-style hat, or elegant, obscuring garbs that are essentially glorified body bags.
