Fashion Face-Off: Paris Hilton vs. Mischa Barton

Paris Hilton hits Cannes wearing the same dress Mischa Barton donned at an L.A. party last fall...but who wore it best?

Is Paris Hilton wearing sloppy seconds at Cannes?

Mischa Barton first wore this Grecian-inspired gown to a DSquared party in L.A. last fall, while Paris picked the frock for a fete in Cannes.

Mischa kept her look fairly simple with a few bracelets, while Paris added a belt and headband to her ensemble.

We give Paris props for her fun accessories, but we're not sure we like the closed-toe shoes she chose with this summery white dress.
