I Wish I Dressed as Cool as This 73-Year-Old Hollywood Megastar

Last week, Diane Keaton disclosed—in all caps—on Instagram that she has not worn colour in over four years. The confession came paired with a picture of her in a hazmat orange voluminous dress while covering her face (#relatable). We've recently charted her new OOTD-style posts, thanking the style deities for such exclusive and completely authentic fashion advice from an actual style icon.

Since posting her outfits more frequently, 73-year-old Diane Keaton has become the ultimate influencer, simply because she already was one long before Instagram existed.

Since her breakout role playing a version of herself in Annie Hall, Keaton's become the most highly referenced master of menswear for women. That iconic look—the relaxed khaki slacks, waistcoat, white shirt and tie—has never been beaten. Since then, she's evolved her look over and over, always sticking to her very own unique, slightly off-beat sense of style.

Through the '70s, she wore neutral layers of beige. In the '80s, she paired leathers together the way Canadians do denim and favoured massive overcoats and floppy hats. The '90s saw her many all-white ensembles, perhaps even inspiring the iconic dance scene in The First Wives Club.

Since then, we've seen her wearing berets, quirky frames, OTT belts and so much more. Over the years, Diane Keaton has proven how to make monochrome exciting while evolving her personal style by incorporating trends and new shapes into her look. Plus, she's unafraid to challenge celebrity fashion expectations.
