When Vogue was producing its September issue in 2007, ad pages were up by 100 from 2006, Neiman Marcus' Burt Tansky lamented that he didn't have enough inventory and nearly $50,000 worth of work was thrown out when Anna Wintour cut pages from one of Grace Coddington's elaborate fashion shoots.

That, of course, was a very different time in publishing and retail. But at Wednesday's premiere of R.J. Cutler's documentary "The September Issue," Wintour insisted that a film chronicling her process these days wouldn't be much different. "It's still the same team," she said as she hurried into the screening at MoMA.

Designers came out en masse — Donna Karan, Carolina Herrera, Oscar de la Renta, Marc Jacobs, Vera Wang, Thakoon Panichgal, Zac Posen, Tory Burch, Jason Wu, Kate Mulleavy and Rachel Roy among others -- curious to see what happens behind the scenes at Vogue. But the truth isn't always pretty, as September 2007 cover girl Sienna Miller learned when she saw Wintour onscreen, scrutinizing her teeth (down to her fillings) in Mario Testino's photograph.

"I think it's just part of the process," Miller said afterward, appearing to take the criticism in stride. She then joined others who stuck around for a postshow Champagne including the film's unofficial star Coddington, as well as André Leon Talley, Diddy, actor Jonny Lee Miller (who’s about to appear with Sienna Miller on Broadway), models like Karlie Kloss and Raquel Zimmermann and late Vogue editor Diana Vreeland's grandson Nicholas, a Buddhist monk.
