Diane Keaton wore her own clothes on the cover of Vanity Fair because you can't improve on perfection.

The annual Hollywood issue of Vanity Fair will come out in March and the theme this year is diversity.

It’s no accident that the cover, shot by the iconic Annie Leibowitz and shared on the magazine’s social media accounts today, features an all-female collection of stars and includes women of colour, as well as older actresses.

The wage gap, lack of parts for women over 50 and the continuing lack of recognition for entertainers of colour — as highlighted by the recent controversy over this year’s Oscars nominations — have all been key issues for the industry in the past 12 months.

This cover is by no means perfect, but it’s a step in the right direction (and a vast improvement on the whitewash that was the 2010 cover).

But look, all of that aside, can we talk about Diane Keaton for a minute?

Even with company like Helen Mirren, Jane Fonda, Cate Blanchett, Jennifer Lawrence and Viola Davis, she still manages to stand out.

Just look at her. Her coat. Her hat. Her cravat. All of it.

Granted she looks a little like she’s just been plonked on the side there in Photoshop (which, let’s face it, she probably was) but, unlike her ball gown-donning contemporaries, she also looks remarkably like herself.

Keaton looks exactly like the grown-up Annie Hall we all know she is and that’s probably because she is the only one dressed entirely in her own clothes.

There is a reason she is smiling for no one else.

Vanity Fair reports:

“According to fashion and style director Jessica Diehl, Keaton’s choice to wear her own ensemble was two parts her singular brand of Keaton spunkiness, and one part her collaborative spirit.

“When Keaton arrived — chipper and ready for her close-up at 7:45 A.M., in her Harnden morning coat, leggings, and studded engineering boots — she began looking through the natty, menswear-inspired pieces Diehl and her team had pulled. “And she’s like, ‘Oh, I love this, I love this,’ and then Annie said, ‘Yeah, I love that too, but you kind of already look great!'”

We completely agree and we’re not the only ones. The Twitterverse has erupted in chorus of Keaton appreciation (Kea-ppreciation?):

Oh, Annie. Never change.
