Mischa Barton is a dirty hippie

I'm all for retro, but Mischa Barton's dress makes her look like a time traveler from the 70's. Only not nearly as cool as that sounds, because if it was there'd probably be a dinosaur in the background having a fist fight with Abraham Lincoln. And you'd put your money on the dinosaur, but old Abe has a mean uppercut.

More of Mischa looking like she's given up showering after the jump.
