Mischa Barton at the amfAR Cinema Against Aids Gala at Cannes on May 20.
Mischa arrived looking ultra glam in a flowing white Marchesa gown and black Louboutin pumps.
Her second look for the event was another Marchesa creation - beautifully detailed with rampant horses and floral embellishments. (That's Diane Kruger with her in the second pic - I always thought she was tall but next to Mischa she looks teeny, who knew Mischa was so lofty.)
Mischa was wearing black and white Christian Louboutin booties with her second look but a sparkling silver Marchesa clutch accessorized both dresses.
