Mischa Barton was spotted leaving Mahiki nightclub in London last night, after attending the No-Tell Motel Southern Comfort Room Launch party.

She scrubbed up very well wearing a MW Matthew Williamson beetle print silk blouse from the Fall 2011 collection, with a yellow pleated Willow Spring 2011 skirt.

I have a bit of a yellow shoe fetish at the moment, so I’m crushing on her Charlotte Olympia platform heels.

Mischa’s blouse is our first peek at a look from Matthew Williamson’s diffusion line.

The designer said he created the line after becoming sick of people saying, “I love it, but I can’t afford it,” with regards to the mainline collection.

So far it looks great; hopefully we’ll get to see more soon.
