The Project RunwayAll Stars designers have a new mentor.

Marie Claire senior fashion editor Zanna Roberts Rassi is taking over for Joanna Coles. Marie Claire has been a longtime partner with the fashion design competition series (the winner receives a fashion spread in the magazine and a yearlong position as contributing editor), but Coles, the magazine's former editor, last year made the jump to Cosmopolitan.
