Actress Michelle Williams attended the Cannes premiere of her new film ‘Blue Valentine’ in a truly terrible dress. The silk off the shoulder gown is totally shapeless and does absolutely nothing for Michelle’s figure or colouring.

The dress is from Chanel’s spring 2010 couture collection which just goes to show that just because a dress cost thousands doesn’t mean it will necessarily look good. You may remember that Sarah Jessica Parker wore a very similar Chanel couture gown to the Academy Awards earlier this year that received similar criticism.
