Rooney Mara Dress at CFDA Awards 2013

CFDA Style Battle: Rooney and Kate Mara Take On the Black Party Dress

Sisters Rooney and Kate Mara both delivered black dresses at tonight's CFDA Awards — albeit each with her own signature style twist. True to form, Rooney delivered a moodier look in a burnout Calvin Klein Collection sheath, which she finished simply with black platforms and a single gold bangle. As for Kate, the actress brightened up her peekaboo minidress with bold Irene Neuwirth jewels and a pair of embellished peep-toes. In short, we've got two very stylish takes on the black dress — but we're asking you to choose just one: which Rooney sister wowed most at tonight's CFDA Awards?
