Best Dressed Of The Week was going to be difficult already then Abbie Cornish throws her hat into the ring to make the decision even more difficult.

At the Vanity Fair & Apparition Present the Premiere of “Bright Star” this week she glowed wearing an Elie Saab Fall 2009.

I was always a fan of Elie’s extravagant blingy gowns, but this simple strapless crepe and silk satin teal gown is to die-for.

Abbie wears it well and her hairstyle gives her look an old Hollywood feel.
