Did you stock your closet with nothing but Heidi Montag's Heidiwood, Mandy Moore's Mblem, Jennifer Lopez's Sweetface, JLO by Jennifer Lopez? If so, get thee to a charity shop because you're probably having a hard time to find your favourite celebrity lines. Those fashion labels have all closed, while Lauren Conrad's collection is, um, taking a break, and Paris Hilton no longer has a collaboration with Dollhouse.

Other celeb-linked lines, which are less focused on the celebrity's name, are faring better, as WWD points out. Think William Rast (Justin Timberlake), L.A.M.B. (Gwen Stefani) and Rocawear (Jay-Z).
