This dress is not all-white...

It looks like Mischa hit the champers BEFORE the party -  even her dress looks tipsy! The top half of her dress is clearly trying to escape and the bottom half is left wondering if it's a tablecloth we are just blinded by the dress.

While Mischa's rock chick, boho style usually ticks all the right boxes, she is sadly losing her edge in the style stakes.

We know the O.C is over, but Mischa should really look back to Marissa for some cool Californian inspiration, before her wardrobes flees her for good!
