Sienna Miller Premieres The September Issue

Sienna Miller rubs shoulders with Vogue‘s high priestess Anna Wintour at the screening of The September Issue at New York City’s Museum of Modern Art on Wednesday (August 19).

The movie gives viewers unprecedented access to the inner workings of Vogue. At the eye of this annual fashion hurricane is the two-decade relationship between Wintour and Grace Coddington, Creative Director and fashion genius. The September Issue opens in NY on August 28 and on September 11 in Los Angeles and select cities.

FYI: Anna wore Prada while Sienna wore a Thakoon dress, gold Jimmy Choos, Bottega Veneta clutch and Erickson Beamon earrings. (Designer Thakoon Panichgul stars in The September Issue.)
