The Met's Costume Institute Gala was last night. The Gala kicked off the new Costume Institute exhibition "Superheroes" Imagery in Fashion (May 7 - Sept. 1, 2008). The gala's Honorary Chair was Giorgio Armani and Co-Chairs George Clooney, Julia Roberts, and Anna Wintour. As usual everyone who is anyone was in attendance.
Here's Anna Wintour in an interesting silver Chanel Haute Couture dress. 
You can see all the photos here.
Here are my votes for the best and worst dresses.
Worst: Christina Ricci in Givenchy Haute Couture
Best: I hate to say it, but Eva Longoria in Marchesa
I'm not a big fan of Eva, but this dress was a great choice. It stands out because of the color and detailing. I also liked Kelly Klein, in a green Calvin Klein Collection dress and Scarlett looked quite good in Dolce & Gabbana with a corset style top.
