Emma Watson attended a special screening of her latest flick ‘The Perks Of Being A Wallflower’ held at the Mayfair Hotel in London last night.

The British actress becomes the third person this week to don a look from the Christian Dior Fall 2012 Couture, after Julianne Moore and Natalie Portman, but Emma opted for something more masculine.

Her black cut-off ballgown was styled with black cigarette pants.

I love the peplum effect of this look, but the hair is too cutesy. Even though she’s done the slicked-back hair and red-lip look several times before, it would’ve really worked to give this outfit an edge.

Emma styled her look with simple black Dior pumps, diamond Boucheron earrings and a silver Tiffany & Co. keys heart pendant necklace.
