We hear the official Style Blogger, Teen Vogue's Kimball Hastings, is leaving his fabulous post. The dapper (and very smart) Mr. Kimball will soon help Ralph Lauren with public relations, specifically the part where young, hip starlets are wrangled into Ralph's older classic silhouettes. "They need it," said our source, "Because the brand has a lot of resources but maybe not that much of a cool factor anymore." We bet Kimball will be perfect at that - in his tenure at Teen Vogue, he convinced Camilla Belle into a Givenchy gown for the Met Ball, and Taylor Momsen into a Peter Som dress for Cannes. We expect to see his famous friends like Mischa Barton and Michelle Trachtenberg in some serious R.L. outfits, plus a name-drop in Gossip Girl that outshines the Erikson Beamon plug.
