Here's the official trailer for Diana Vreeland: The Eye Has To Travel, the documentary about the legendary fashion editor directed by Lisa Immordino Vreeland (who is married to Vreeland's grandson). "The fashion world changes all the times. You can even see the approaching revolution in clothes," says Vreeland in interview file footage. "You can see and feel everything in clothes." (Anna Wintour is reportedly fond of a similar construction, "If you look at any great fashion photograph out of context, it will tell you just as much about what's going on in the world as a headline in The New York Times." But when prompted for an example in 2007, all she could point to was clothing that looked "militant and urban" that carried "a sense of going into battle." When Vreeland makes her point about how fashion both reflects and influences the wider world, she does it with conviction.) In the film, industry luminaries including Manolo Blahnik, Diane von Furstenberg, and Calvin Klein talk about how Vreeland — first at Harper's Bazaar and later at Vogue and the Met's Costume Institute — modernized the world of fashion magazines. She covered hip, young stars like Mick Jagger and Barbra Streisand and socialized at Studio 54. Of course, she could also be famously difficult to work for. The film comes out in September.
