Mischa Barton Dons Dior

Former O.C. star Mischa Barton goes for clean and simple in classic white and black on Tuesday morning. Mischa, 21, arrived for the Christian Dior Ready-to-Wear fashion show at Jardin des Tuileries in Paris, France.

Mischa co-stars with Hayden Christensen in Virgin Territory, scheduled for an Aug. 24 release.

Virgin Territory is a romantic-comedy film based upon Giovanni Boccaccio‘s Decameron, which tells the story of young Florentines in the countryside telling one another stories about love and adventure as they wait for the plague to end in the city.

Virgin Territory also co-stars Christopher Egan (Vanished) and Rupert Friend (Keira Knightey‘s boyfriend).
