Mischa Barton wore a long-sleeved black gown from Temperley London's fall 2012 collection to the launch of Johnnie Walker Gold Label Reserve in London last night. She accessorized with black pumps.

Aside from her bare shoulders, this look is pretty covered up. Should she have picked something more summery? Or do you enjoy a good medieval dress in July?
