Mischa Barton wore a maxi dress to the Serpentine Gallery's annual Pavilion Party at Kensington Gardens last night in London. She accessorized with a handbag and a couple of rings.

It appears that the hem of her dress was dragged through the mud. Should she have worn a shorter dress to the outdoor event? Or do you like the floor-sweeping look?
