Dress the Woman You Are: What Diane Keaton Taught Us About Personal Style

Diane Keaton died on October 11, 2025, at the age of 79. A year later, fashion pages are still writing about her. In October, the Dutch magazine Elegance marked the anniversary with a look back at Annie Hall, while her children, Dexter and Duke, shared family photos in her memory. It is easy to see why she stays with us. In an industry that so often asks women to change, she spent more than fifty years looking exactly like herself.

The clothes came from her own closet

In 1977, Keaton played the title role in Annie Hall, and the following spring she won the Oscar for best actress. The character was modeled on her, down to the name: Keaton was born Diane Hall. So were the clothes. Much of what Annie wears, the wide trousers, the vest, the tie and the floppy hat, came from Keaton's own wardrobe. Costume designer Ruth Morley questioned some of the combinations, but the director let Keaton dress the part her way.

After her death, The New York Times put it in one line. When other women copied those outfits, they looked like costumes. For Keaton, they were an ethos.

A thrift store, a camera and a lot of work

Her eye for clothes started early. Her mother, Dorothy, an amateur photographer, took her shopping in secondhand stores. "She took me to Goodwill and let me express myself," Keaton told People.

That creative drive never stopped at acting. In 1980 Keaton published her first photography book, Reservations, with Knopf: black-and-white pictures of empty lobbies and banquet halls in American hotels that she shot in the 1970s. She directed films, among them Unstrung Heroes in 1995 and Hanging Up in 2000. She wrote memoirs, starting with Then Again in 2011. And she built a lucrative sideline in buying run-down houses, restoring them and selling them on, a habit The Guardian traced back to childhood visits to houses with her father, a real estate agent. Behind the famous hat was a woman who never stopped working.

One look, fifty years

What fashion editors keep coming back to is how steady she was. The Times noted that she kept one recognizable look for more than half a century. She let it grow, with scarves instead of ties and long skirts instead of trousers, but she never let it go. In 2024, she summed up her formula for People: "a turtleneck, suit, large belt and of course a hat and glasses!" Then she added, "Some things will never change for me."

That certainty found her a whole new audience online. In 2019, at 73, she had 920,000 followers on Instagram, and according to the Los Angeles Times, she wanted a million. In 2022, a younger generation discovered her wardrobe from the 2003 film Something's Gotta Give on TikTok, and it started a trend of its own.

Find your own formula

Keaton's lesson was never about the hat. It was this: work out what makes you feel most like yourself, then wear it again and again until it belongs to you. A signature does not need to be loud. It needs to be repeated.

Start with a suit in one shade. Tailoring was the backbone of her style, and a jacket and trousers in one color is the simplest place to begin. The Rosie Cropped Blazer in light brown ends at the waist with a gold-tone buckle, a sharp, short line that feels modern. In cream, The City Look pairs the Rosie with the high-waisted, straight-leg Alani trousers, and The Meeting Look does the same with the longer Amor Corset Blazer. Wear it to work on Monday, again on Thursday, and let it become the look people know you by.

Keep the tailoring for evening. Even at the Academy Awards, The Times wrote, she looked like herself, in trousers and a hat. For your own evenings, keep the jacket and change the hem. The Cocktail Look in cream puts the Rosie over the Isabel mini skirt, and The Dinner Look in light brown does it with the Amor.

Choose one color from top to hem. For dinner at a friend's house, the Zaila Double-Layered Crop Top with the Isabel Mini Skirt, both in light brown, gives you one warm shade from shoulder to knee. It is the same idea as her suits: fewer decisions, more you.

The point was always her

What made Keaton unforgettable was never one hat or one suit. It was the sense that she knew exactly who she was, at 32 on the Oscar stage and at 79. That kind of style can be borrowed by anyone and copied by no one. Find the pieces that feel like you, wear them often, and let them become part of how people remember you.
