Mischa Barton's having a nice day out. She walks around, she goes to the dog park, she gets something out of her car, and BAM! A little breeze hits her muumuu top, blowing it up a bit, and there's her can for all the world to see.

Did Mischa not realize that her little nude colored leggings are completely see-through? Or may she did.....

Perhaps the gainfully unemployed 'O.C.' actress is trying to get a little Britney/Lindsay/Paris type mileage from her saggy ass.

Nice try, Mischa, but no dice.
