MISCHA BARTON looked gorgeous in a summery yellow gown as she attended the Serpentine Gallery Summer Party in Hyde Park.

Looks like Mischa is officially done looking like a mess when she goes out in public.

The once troubled actress was quite stunning in a sleeveless, figure-hugging Luisa Beccaria gown, which she accessorized with a mint green purse.

Mischa finished the look with a simple updo with face-framing tendrils, shimmery bronze eye makeup, and bombshell red lips.
