Ashley Greene and Blake Lively

Who will win the battle: 'Twilight' vampire Ashley Greene or stylish 'Gossip Girl' socialite Blake Lively? Call it a war with two winners as they both look stunning.

Ashley Greene and Blake Lively sport black and white versions of this Antonio Berardi knee-length sheath dress.

Greene hit the red carpet in cream last May, accessorizing her frock with black peep-toe pumps, dangly earrings, and a messy updo.

Lively wore the curve-hugging number in black at the Fenway Park premiere of her new film, Ben Affleck's 'The Town.' A little overdressed for the ballpark Lively paired her LBD with nude heels and a chic ponytail. Lively has won raves for her performance in the critically-acclaimed film.
