Once, twice, now it's three times that we've spotted Harry Potter hottie, and recently announced Alberta Ferretti collaborator, Emma Watson wearing black for the Deathly Hallows press tour. Perhaps Emma's in mourning for her alter-ego Hermione? Whatever the reason, we like this black dress fetish of Emma's, and the slinky Calvin Klein number she wore to the Harry Potter and the Deathly Hallows NYC premiere today is no exception. The scooped back, cross-over style flashes some flesh without being too revealing, and it's a nice change from the shorter LBDs that we've spotted everywhere of late. What's your take on Emma's NYC look? (Oh, and if you still want more Deathly Hallows deets, head to Pop for the scoop!).
