On a night that's all about fashion, it's fitting that some of the best red carpet model scouting of the year comes at the Costume Institute Gala at the Metropolitan Museum of Art. On this night, the model's don't just come on the arms of A-List stars, they are the stars of the evening themselves. Many of them - Gisele Bundchen, Raquel Zimmermann, Naomi Campbell, Karen Elson and Coco Rocha - wearing the true star of the evening, Alexander McQueen, whom the 2011 exhibit is a post-humus tribute to.

It is also traditional for models to wear a dress by the designer at whose table they are seated, such as Jessica Stam in Tommy Hilfiger, Natalia Vodianova in Valentino, Doutzen Kroes in Giambattista Valli and Rosie Huntington-Whitely in Burberry.
