Elle Fanning vamps it up in plunging black gown at About Ray premiere with her trouser-clad co-stars Susan Sarandon and Naomi Watts

Elle Fanning vamped it up in plunging b&w high-low gown at the Toronto International Film Festival's world premiere of About Ray on Saturday.

It was a very different look for the effervescent blonde, who rocked edgy red eye-liner and no lipstick with her side-parted flaxen locks.
