Dakota Fanning was back at work on the set of Very Good Girls in Brooklyn yesterday. She sported an oversized denim button-down and biker boots while filming and was joined by costar Elizabeth Olsen. The pair have been shooting scenes in the Big Apple recently. Last week, Dakota and Elizabeth rode bikes while filming and caught up between takes. The film, which was written by Jake Gyllenhaal's mom, Naomi Foner, paints the girls as best friends who fall for the same guy. It also stars Richard Dreyfuss and Demi Moore, who was on set yesterday as well.
