Elizabeth Olsen attended a screening of her new and alliterative film Martha Marcy May Marlene in New York last night, wearing head-to-toe Alexander McQueen. The sleeveless black dress with a ruffly skirt is from the fall 2011 Alexander McQueen collection; she accessorized with jewel-embellished black peep-toe wedges and a skull clasp clutch.

This is a darker, more sophisticated look for Elizabeth — how do you feel about her new edgy glamour?
