Mischa Barton at the launch of Marc Jacobs' new fragrance - Bang.
In London for the July 22 event, Mischa wore a dress and matched it with black Chanel pumps.
It's a real change from the style she was seen in just days before while at an airport in France - she was in some blue Levi jeans and her yellow Louboutin lace-ups. I'm not going to say what her t-shirt stated but it's an Erin Wasson design and you can take a better look at it here.
