TIFF fashion look we love: Olivia Wilde is Greek goddess gorgeous

Olivia Wilde arrived at the premiere of Butter looking a-a-a-a-mazing in this white floor-sweeping Marchesa (one of the designers is the talented wife of Harvey Weinstein) gown. The dress was such a showstopper that she didn't need much makeup and kept her look neutral with her hair up in a simple bun.
