Meryl Streep has joked she's suffering "PTSD from wearing high heels for 16 weeks" while filming The Devi Wears Prada sequel

She told Vogue magazine: "As a person holding her position for 20 years, [Miranda] kept her look but adapted it, as we do with time. But I almost had PTSD from wearing high heels for 16 weeks. I feel like I should get a Medal of Freedom!"

Meryl added her character's look for the new film is "more sleek, stylish, and clean" than in the first.

The sequel reunites Streep with her co-stars Anne Hathaway and Emily Blunt, who return as Andy Sachs and Emily Charlton respectively.

Emily returns to a red bob for her role but she's admitted she had to wear a wig for the shoot because dyeing her hair would have been too much hassle.

She told Vogue: "You see a flash of it [the red hair] and people know it's her [the character]. But it was a wig - that kind of red is too hard to maintain!"

Anne's character Andy is seen sporting a fashion-focused wardrobe in the second film and the actress admitted she needed a story to explain how a reporter working these days could afford designer gear - revealing she came up with the idea that Andy must be a fan of thrift stores.

She told the publication: "I made it an actual story point in the film that we had to explain how somebody who, working as a writer in these times, could have a fabulous wardrobe.

"I pitched that Andy went on to do investigative journalism, traveled the world for 15 years... and when you've had an education at a place like [fictional magazine] Runway, you know what to do when you see a consignment shop. So she's been thrifting for the better part of 20 years."

Anne went on to insist she hopes the film's release inspires fans to dress up for their outing to the cinema, saying: "I'm hoping everybody dresses up and goes to the movies.

"I hope people remember how much fun they had wearing hot pink and going to see Barbie. I'm hoping that everybody puts on their favorite Miranda Priestly-approved outfit and just has a blast."
