Diane Keaton isn't a fan of 'terrible' boots she wears in Mack & Rita

Diane Keaton isn't a fan of the "terrible" thigh-high boots she wears in her new movie Mack & Rita.

The Annie Hall actress generated a lot of attention on social media in June when the trailer for the comedy film was released, with the clip depicting Keaton's character Rita attempting to walk in a pair of grey snakeskin-look boots.

But in a new interview with Vogue, the star admitted she would never be spotted wearing the footwear in her real life.

"I wouldn't go so far as to wear the clothing that's on the billboard. It's terrible, are you kidding? That white thing with that belt around my waist... and those legs?" she sighed. "I've never seen anything worse. And the fact that we put on those leggings with those boots? I mean, that's scary."

However, Keaton - who is known for her lifelong love of monochromatic outfits - confessed that she had "a lot" of input in the costume design.

"Are you thinking I didn't pick out those clothes with help? I did. That was my choice. I'm taking the hit for that one. Of course, the hair too-lovely," the 76-year-old continued. "It says that I'm also a co-producer down at the bottom there, so they had to deal with me. I made some perfect choices for that character."

Mack & Rita follows a 30-year-old woman named Mack, as played by Elizabeth Lail, who wakes up as her 70-year-old self, as portrayed by Keaton, after a bachelorette party in Palm Springs.

The film, which also features Taylour Paige, Martin Short, and Dustin Milligan, is now showing in U.S. cinemas.
