Lisa Arbetter has been appointed editor-in-chief at People StyleWatch. Her appointment follows the departure of founding EIC Susan Kaufman, who was ousted in January. Arbetter will work under Ariel Foxman, whose role expanded from InStyle‘s top editor to editorial director at InStyle and People StyleWatch in late January. Arbetter was most recently the deputy editor at InStyle; she has been in that role since 2009. Arbetter had previously worked at People StyleWatch as deputy editor for two years when it launched in 2007. “Lisa is a brilliant editor, a business-minded strategist and open-minded collaborator,” Foxman said in a statement. “That–coupled with her sophisticated understanding of the needs and wants of the fashion and beauty–obsessed consumer–makes her the perfect partner to lead StyleWatch into its next exciting and innovative phase.”
