Pick of the Week: Harvey Nichols

Katherine Levy is a fan of the Harvey Nichols Christmas spot, by Adam & Eve/DDB: "This stylish ad is a twist on the dilemma of how to behave when another female wears the same party dress as you. Bringing Harry Potter/Doctor Who/Bewitched-style sorcery to the party proceedings, the ad focuses on one product rather than blinding the audience with a selection of dresses like so many Christmas campaigns." It was created by Mike Crowe and Rob Messeter, and directed by Ne-o through Stink.
