You may remember her as Scarlett Johansson's brunette counterpart in Vicky Cristina Barcelona, but you'll soon know Rebecca Hall both for her performance in The Town and her chic style choices. pointed out today that the actress, who stars alongside Ben Affleck, Jon Hamm and Blake Lively in the new film, has been turning heads on the red carpet as of late. We first took note when Hall wore a stunning turquoise blue Vionnet gown (center) for the film's debut at the Venice Film Festival. And she wore the French label again, this time choosing a demure black lace number (right), for the London premiere this morning. Another standout choice? The chic red and pink Bottega Veneta dress (left) she wore in Boston last week for the U.S. premiere.
