The Costume Institue Gala is New York's event of the Year, where star's arrive and showcase the best of Couture. Some lucky stars even get to walk the red carpet with their favourite designer. This years theme was superheroes, so as you would expect, most of the dresses were out of this world, but some did suprisingly fail to impress.
Best dressed of the night - Mischa Barton
Worst Dressed of the night - Fergie (looking at the expression on the face, maybe she walked passed a mirror and realised she wasn't looking her best).
