Carey Mulligan: 2012 Met Ball Co-Chair!

She has a big role in the extravagant affair, and Carey Mulligan was spotted arriving for the 'Schiaparelli and Prada: Impossible Conversations' 2012 Costume Institute Gala in New York City on Monday (May 7).

The "Drive" darling turned heads as she passed through the Metropolitan Museum of Art venue while clad in a gorgeous black Stella McCartney dress adorned with a lacy texture.

The annual fete finds Miss Mulligan acting as honorary co-chair alongside designer Miuccia Prada and US Vogue editor-in-chief Anna Wintour, while Azealia Banks is lined up to perform.

As for the celebratory occasion, this year's rendition of the Met gala ushers in the 'Schiaparelli and Prada: Impossible Conversations' exhibition exploring "the striking affinities between Elsa Schiaparelli and Miuccia Prada, two Italian designers from different eras."

The display is described as being "inspired by Miguel Covarrubias's "Impossible Interviews" for Vanity Fair in the 1930s while featuring "orchestrated conversations between these iconic women to suggest new readings of their most innovative work."
