My big three for best dressed were Halle Berry, Reese Witherspoon, and Marcia Gay Harden (although her hair was unfortunate.)
I just wanted to slap Cameron Diaz silly for showing up like she'd rolled right out of bed. I was very disappointed in general with the fashions this year...they spend THOUSANDS of dollars on stylists and makeup artists and they don't look fit to leave the house?!?! That's ridiculous.
