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.

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.

Wide leg crepe trousers from M&S

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.

Merino wool turtleneck top from Cos

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.

Wool fedora from All Saints

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
