According to WWD, Christian Dior's pre-fall collection "took inspiration from two distinct aesthetics: Alfred Hitchcock’s icy heroines and Helmut Newton’s tough-chic glamazons."
While I agree, I would also insist that John Galliano had Gossip Girl looping through the studios as he designed the collection. This look, in particular, is so Lily van der Woodsen - right down to the sassy strut, the blase sunglasses worn indoors, and the wrought-iron stairway.
On second thought, or so Daisy Buchanan, depending on your school of thought (i.e. old school vs. new school).
