Michelle Williams has been busy at the 2008 Cannes Film Festival promoting her latest movie Synecdoche (see a few clips over at Buzz). She appeared at the photocall wearing a casual yet feminine outfit teaming feminine prints and pleats with a navy blue blazer. Later she changed in to something more glamorous appearing on the red carpet in a floor length tiered gown. Michelle has also made an appearance in a vintage style lace dress. Which look do you prefer?
