Lily Collins' Changing Looks

Collins wore her nearly waist-length locks perfectly straight.

For the London premiere of The Dark Knight, Collins pulled her hair back into a simple ponytail that put her glowing skin on display.

She hit the Hollywood Style Awards wearing ringlets and shimmering bronze shadow.

For the Abduction premiere, Collins showed off her new hair color (darkened for her role as Snow White in Mirror Mirror) and very Audrey-esque faux fringe.

"It's always great to try new styles with Lily," hairstylist Thomas Dunkin said of the star's sleek strands at a Chanel event. "This time we wanted to try a very graphic look."

Collins dyed her strands a deep shade of burgundy red for her upcoming part in The Mortal Instruments: City of Bones. "It's not-in-your-face kind of red," she told us of her new hue when she stopped by the InStyle portrait studio at the Toronto International Film Festival.
