Best Dressed at the 2009 Oscars: Amanda Seyfried

I think Miss Amanda is one of the best young actresses out there, and that's not because of Mamma Mia at all. It's more because of Big Love, where she has done an amazing job with her role.

That being said, look at her dress! Gorgeous. And it's Valentino Couture, from the Spring 2009 collection.
