Olivia Wilde At The Toronto Film Festival: Love It Or Leave It? (PHOTOS)

Olivia Wilde has one of the best bodies we have ever seen. Period. So it's a wonder that she loves covering it up in long, flowing dresses that could double as tents, as she did at VH1's Do Something Awards and at the premiere of her summer flick, "Cowboys & Aliens."

Last night at the Toronto International Film Festival, the star of "Butter" arrived the premiere of her new movie as well as InStyle And The Hollywood Foreign Press Association's Annual Event wearing a white Grecian-style gown by Marchesa with dramatic metallic collar and cuffs.

Posing with her "Butter" co-stars, including Ashley Greene, Jennifer Garner and Alicia Silverstone, Wilde skipped the jewelry (which was a really good call, given her dress's built-in gilt) and carried a small metallic clutch.

The diaphanous quality of the dress was pretty, but we wonder why the 27-year-old starlet continues to dress in old-lady shapes that hide her figure... what gives, Liv?

Below, take a look at the outfit from every angle and tell us: love it or leave it?
