Anna Wintour initially rejected the Vogue cover, but the famous actress eventually persuaded her.

Namely, as her staff revealed on Vogue's podcast "The Run-Through," the process of arranging it was not straightforward, but Anna Wintour could not say "no" to Meryl Streep. Wintour had previously declined cover requests, according to newly appointed editorial content director Chloe Malle. What happens when you put Meryl Streep and Anna Wintour—the two Mirandas, as it were—in a room together? A wide-ranging conversation about fashion, family, friendship, and yes, the forthcoming sequel to “The Devil Wears Prada.” “In terms of Miranda, and coming back to that… pic.twitter.com/apaEAk79MA Chloe Malle pitched the idea of a joint cover to Wintour during Paris Fashion Week last October, shortly after taking on her role. "I said, 'Well, Anna, it would be kind of incredible for you and Meryl to be on the cover,' and she said, 'Well, Chloe, that's very flattering, but it's just not my style,'" Malle revealed. However, later, Meryl Streep posed the same question to her, and the answer was different. Both women, the "fictional Miranda Priestly" (Meryl Streep) and her real-life inspiration (Anna Wintour), wear custom Prada creations on the cover or, as Malle put it: "Two devils, two Pradas." The shoot, credited to Annie Leibovitz, was kept under strict secrecy for months. Malle said the project made Pentagon documents look like Richard Scarry books. Virginia Smith, Vogue's global fashion director, described the process of ordering clothing as a puzzle of vague references to the shoot and, later, outright lies. Despite the secrecy logistics, the two cover stars easily clicked. Smith noted that during a fitting at the Crosby Hotel, Streep and Wintour walked in wearing matching sunny yellow scarves entirely unplanned. Incidentally, the cover arrives just ahead of the film, as well as on the eve of the Met Gala. The role of Miranda Priestly was inspired by Wintour, and the editor has embraced the connection to the role multiple times throughout the year, from appearing at the Oscars with Hathaway to meeting Streep at Milan Fashion Week last fall.
