We haven’t seen much of Mischa Barton for a few months, then the last few days she seemed to be everywhere, which is why it’s not surprise to see her on the red carpet at the 2010 amfAR’s Cinema Against AIDS Gala this evening.

The former ‘OC’ actress opted for a white satin chiffon draped Marchesa Fall 2010 column gown with a ruffled off-the-shoulder neckline.

Judging by this look I’m guessing Mischa was going for a sweet yet naughty look, because her ethereal gown is worn lower than the models plus she’s opted for some heavy eye make-up.

The low neckline I like, but I’m not fond of the dark eyes.

To complete her look Mischa carried a diamond crystal Marchesa clutch.
