Former "O.C." star Mischa Barton did her best "Memoirs of a Geisha" impression last night in L.A. -- where she rocked some crazy neon makeup for a charity event.
Mischa, along with actor Adam Goldberg, hosted a special benefit concert on Thursday at the Bootleg Theater -- where proceeds went to the Japanese Red Cross to aid relief.
While her get-up and face paint probably had something to do with the event's cause, Barton is no stranger to wild style.
Check out a gallery of some of her biggest fashion hits and misses above!
