Of the three girls who wore Louis Vuitton at the Met for the Costume Institute Gala 2009, Kerry Washington' outfit looked the best. She chose Look 1 from Louis Vuittons Fall / Winter 2009/2010 show and altered it a bit so that her boobs were covered. As a result, she looked wonderful. Not too costume-y.

Leighton Meester wore Look 35 from the Louis Vuitton Fall / Winter 2009 - 2010 collection. I like the dress, but  the leggings were a bit much. However her hair and make up were impeccable. 

And here's Madonna. Horrible. She looks fantastic for her age, but no 50+ should dress like this. Thigh high boots, NO! Super short dress, NO! Costume-y hat, NO!
