Proof That Diane Keaton is an Unparalleled Style Original

Keaton fittingly channeled Annie Hall to accept the Best Actress Oscar for her role in the film at the 1978 Academy Awards.

Checkers and two different types of stripes? Keaton went all out with prints for one of her first looks of the ‘80s.

She once again opted for a skirt suit at a New York screening of Unstrung Heroes.

The turn of the century marked the start of Keaton’s tinted glasses and statement belts era, as seen here at the Los Angeles premiere of What Women Want.

Keaton kept it classic to attend the spring 2023 Ralph Lauren show in San Marino, California where she wore a crisp white turtleneck, black overcoat, and a wide-leg pair of high-waisted trousers.

For the New York City premiere of her film Book Club: The Next Chapter (which she stars alongside Jane Fonda, Candice Bergen, and Mary Steenburgen), Keaton opted for a black-and-white horizontal striped trench that she belted at the waist.

The actress cracked the code to pattern clashing with pinstripe pants and a houndstooth trench for the Ralph Lauren spring 2024 show.

Thom Browne is a natural fit for Keaton, who wore the brand’s signature suiting (and a wicker dog-shaped bag) to their couture runway show in Paris.
