Lily Collins Channels Her Inner Vamp

We're not used to seeing Lily Collins looking so grown up (or at least trying to).

The actress, who was spotted signing autographs in Philadelphia in time for the release of her new film, The Mortal Instruments: City Of Bones, wore a black and red shirt and black mini skirt for the event. Dark nails and a red lip accented her look.

It's the Pretty Woman-esque boots, however, that have us scratching our collective heads. Perhaps Lily is trying to shake off her fairytale roots courtesy of her starrig role in last year's Mirror Mirror ahead of her new outing as a half-Angel demon hunter?

Whatever the reason, we're not sure she's pulling this look off. It's a little more girl-playing-dress-up-in-Julia-Robert's-closet than ingenue-breaks-out-of-her-shell.
