I was just about to put together the BDOTW post when I saw this gorgeous picture of Michelle Williams on the red carpet tonight for the 2010 London Film Festival Premiere for “Blue Valentine.”

The platinum blonde actress wore a beautiful Erdem ‘Margot’ red lace dress from the Spring 2010 collection with 3/4 length sleeves.

Her dress is slightly longer from the runway, but it doesn’t take anything away from her look.

What I love most about this look – apart from the dress – is the quiff and the animal print Charlotte Olympia heels.

Thank god they’re not matching her Charlotte Olympia clutch.

A very late BDOTW contender.

If you’re wondering about the hair colour, Michelle is currently filming “My Week With Marilyn” in which she plays the iconic Marilyn Monroe in the biopic.
