Diane’s enduring influence is rooted in her fearless individualism, authenticity, and bold departure from the traditional celebrity glamour. Instead, she embraced individuality and comfort, a commitment that set her apart from other Hollywood stars who often conformed to the red carpet norm.
Designers like Ralph Lauren, Thom Browne, and Phoebe Philo have acknowledged Diane’s enormous impact. Keaton’s style has inspired new generations who embrace her “effortlessly cool” aesthetic and vintage-inspired looks.
News of her untimely passing came just days after “Fashion Month” officially ended in Paris. It’s impossible to look back and not see Diane’s incomparable imprint.
I could easily imagine her wearing many of the best designs. If nothing else, they bear Keaton’s inimitable seal of approval. Keaton famously wore both tailored and oversized clothing, often blending the two styles in a way that defined her unique look.

Beginning with Keaton’s role in the 1977 film Annie Hall and remaining consistent throughout her life, Keaton was known for her androgynous, menswear-inspired aesthetic, comprised of oversized blazers, vests, ties, and turtlenecks worn in a relaxed and eclectic way.
Elements of Diane’s style featured a relaxed, slouchy fit. She frequently wore men’s blazers and other jackets that were intentionally too big, creating a boxy and comfortable silhouette. Keaton’s use of ties was another key element of her androgynous, menswear-inspired look.

Diane was a trailblazer, breaking from the fashion norms of her time. She fearlessly incorporated ties into her looks, and many of the costumes from the film were straight from her own closet, cementing her unique and influential fashion sense.

As Keaton’s style evolved over her career, her color choices shifted along with it. Even as Diane embraced black and white, Keaton’s style continued to incorporate a variety of neutrals.

Keaton’s effortlessly chic look in “Something’s Gotta Give” (2003)—with its reliance on a white, ecru, and sand color scheme—became iconic for its comfortable, “coastal grandma” chic.
Keaton was famously known for her red carpet tuxedo style, which became a signature part of her androgynous, menswear-inspired fashion. Her confident and unconventional approach defied traditional red carpet glamour, emphasizing individuality and often featuring a preference for a black-and-white color palette and the use of bold accessories.

Crisp white shirts, especially with French cuffs, were a staple of Keaton’s style, worn both with formal menswear and casual high-waisted jeans. Diane often completed her look with a crisp white shirt underneath a jacket.

Diane had a deep love for wide-legged jeans, which she has worn consistently throughout her career. Keaton has often spoken about their versatility and her personal satisfaction with the style, stating that she’s received more compliments on a specific pair of wide-leg jeans than anything else.

An exuberance defined Diane’s style, so it was not surprising that she gravitated to polka dots. She loved polka dots and featured them in many of her iconic looks. She once called them “the wonder of the world” and incorporated them into her signature style through accessories like ties and scarves, as well as skirts and dresses.
