There's an effortlessness to Diane Keaton's best looks that she has cultivated during five-plus decades in the spotlight. From awards ceremonies to showbiz events, she has wowed on the red carpet in adventurous looks featuring sleek belted suits, voluminous layering, a neutral colour palette and swathes of gingham.
Keaton's career began in the Broadway productions Hair and Play It Again, Sam in the late 1960s, with her first major film role coming in 1972's The Godfather. The star then appeared in several films produced by Woody Allen - her former partner - from the 1970s. In the decades that followed, she was cast in big-screen hits such as Reds, The First Wives Club, Something's Gotta Give, Father Of The Bride and Book Club.
The star, who is a mother to two adopted children, became known for her unique fashion sense in the 1977 film Annie Hall, for which she won an Oscar for Best Actress. Her character's wardrobe featured predominantly vintage men's clothing, including fedora hats, baggy trousers and ties. Since then, she has been considered an androgynous style icon, and some have credited her with making trousers suits a popular look for women.
Some core components thread together Keaton's go-to outfits. The Hollywood stalwart favours black, white, grey and beige shades, and classic prints like gingham, polka dot and tartan. Additionally, the actress knows how to style a trouser suit for any occasion, is a fan of a chic turtleneck and isn't afraid to play around with silhouette proportions. She also elevates her looks with cool accessories, frequently stepping out in oversized belts and bowler hats.
Diane Keaton's best looks
From rocking the best tuxedos for women to showcasing some of best red carpet looks, Diane Keaton knows how to create an impression.
1. The Ralph Lauren tailored ensemble
All eyes were on Keaton as she attended the Ralph Lauren fashion show in San Marino, California in 2022. The star stood out in a pair of black high-waisted wide-legged tailored trousers, which she styled with a white top, long-line blazer jacket and black bowler hat.
RRP: £29.50 | If you want to copy Keaton's signature look, the first thing you'll need is a great pair of smart black trousers. We like these wide-leg crepe trousers from M&S. Size up for a slouchy, cool look.
RRP: £45 | Next, you'll need a classic turtleneck. Keaton's signature starchy white shade is eye-catching but won't work for everyone; instead, we like this versatile hue from Cos.
RRP: £79 | Where better to get a fedora than from the cool-girl brand, All Saints? This wool hat is truly all ages and will add a little edge to any outfit. Not sure how to style it? Then look to Keaton for endless inspiration.
2. The classic tartan midi skirt
We love a classic print, and red tartan is a particularly timeless pattern. Keaton stepped out in an eye-catching midi skirt at the Hollywood Film Festival Awards Gala in Beverly Hills in 2005. She paired the eye-catching number with a black turtleneck knit, silky black gloves and classic black heels.
3. The slouchy gingham dress
Keaton has fun playing with the proportions of her clothes. At an event in Los Angeles in 2019, the star stepped out in a slouchy black and white long-sleeved gingham midi dress that featured a voluminous skirt. She accessorised the tulip dress with a neck scarf in matching fabric, an oversized black belt and a pair of classic black boots.
4. The high-necked green polka dot dress
If there's one person guaranteed to rip up the sartorial rulebook at A-list parties, it's Keaton. The actress attended a charity event in Beverly Hills in 1993 in a green and white polka dot maxi dress, which she teamed with a white beanie hat, layered long pearl necklaces and a pair of white brogues. Could she look any cooler?
5. The chic black turtleneck look
Keaton knows that a black turtleneck is a key component of any capsule wardrobe. The actress looked chic at the Today show in New York in 2023 wearing the classic lightweight knit, along with a pair of black tailored trousers and black boots. She finished off her look with sleek locks and minimal make-up.
6. The belted white trouser suit
Keaton wowed in white at a Los Angeles charity event in 2017. The actress looked stylish in a trouser suit, which she cinched in at the waist with an oversized belt. She finished off her sharp ensemble with a bowler hat, turtleneck top and heels.
7. The quirky metallic layered look
Keaton is an enthusiastic fan of layering. The actress wore a black turtleneck beneath a short-sleeved metallic shift dress - in an easy styling trick for making any party dress more suitable for chilly temperatures - at the premiere of the film Love The Coopers in Los Angeles in 2015.
8. The chic silky green scarf
While Keaton may prefer a neutral colour palette, she will add a bright shade to her ensembles on occasion. The actress elevated her all-black look for the Los Angeles screening of the film Brooklyn Laundry in 1991 with a silky green scarf. She paired the eye-catching accessory with a black leather jacket and black heeled boots.
9. The belted red leather jacket
Keaton looked stylish on the red carpet at a gala in Los Angeles in 2003. The star wore a red leather three-quarter-length coat, which she cinched in with a skinny black belt. She paired the statement look with a black trilby hat, black leather gloves and a pair of black heeled ankle boots.

Looking for the best jeans for a more relaxed look? Then take inspiration from Keaton's wide-legged jeans. The actress exuded effortless style while out in a navy-wash pair in Los Angeles in 2019. She wore them with a white turtleneck and a brown leather coat, as well as an oversized brown belt and brown boots.
11. The Golden Globes aviator jacket
It's not a look for everyone but it's one of her get-ups that we'll always remember. Keaton pulled off one of the edgier looks in Golden Globes red carpet history when she arrived at the glamorous event in 1994 in a brown aviator-style jacket. She paired the casual piece with a yellow gingham maxi-skirt and finished off her look with a black clutch bag and black boots.
12. The classic 'shirt and jeans' combo
One of Keaton's key approaches to fashion is simplicity. At the Los Angeles premiere of the film Because I Said So in 2007, the actress looked sharp in a classic white shirt, blue slim-fit jeans and heels. She accessorised with layered black necklaces and a brown belt.
13. Owning the red carpet in elegant belted tailoring
This look brings together two of Keaton's go-to styles: monochrome palettes and smart tailoring. The star turned heads in this white trouser suit, cinched in with an oversized black belt at the And So It Goes film premiere in New York in 2014. She finished off the fresh look with dewy make-up and a chunky silver necklace.
14. The classic white turtleneck look

We also love her sleek grey bob - one of the best bob hairstyles - which complements the eye-catching blue coat perfectly.
16. The sweeping black maxi skirt
We love a black maxi skirt for a sophisticated evening look. Keaton turned heads in one at a film industry gala dinner held in her honour in New York in 2007. The actress paired it with a long-sleeved white shirt, an oversized black patent belt and a monochrome choker necklace. A timeless long skirt outfit idea that would still work today.
17. The cool belted coat look
Keaton demonstrated a savvy way to give a baggy coat a dose of stylish shape at an event in Los Angeles in 2004. The star layered an eye-catching checked three-quarter-length coat over a black turtleneck jumper and black trousers - and cinched in the look with an oversized black belt. She accessorised with a black bowler hat and a black clutch bag.
18. The all-white Golden Globes look
In a dazzling turn, Keaton wowed in an all-white look on the red carpet for the Golden Globe Awards in 2004 - during which she won the Best Actress gong for her role in the film Something's Gotta Give.

We love a pair of printed trousers to jazz up an otherwise plain look. Keaton stepped out in a white pair emblazoned with black polka dots while running errands in Los Angeles in 2014. The star paired them with a black bowler hat, a black three-quarter-length coat and black heeled boots.

There is no stopping Keaton's love of black and white gingham print. The actress wore the classic pattern on a blazer for Jimmy Kimmel Live in 2017. She paired it with a white shirt, oversized black belt and black leather midi-skirt, and accessorised with white socks and black heeled boots.
23. The classic brown leather jacket

At a charity gala in Los Angeles in 2018, Keaton mixed things up in a chic all-brown look. The star wore a tuxedo-style double-breasted blazer jacket that matched her wide-legged trousers, which she layered over a turtleneck. She finished off her look with a bowler hat and oversized belt.
