According to WWD.com, celebrity fashion lines seem to be losing their luster with the public. From designers J. Lo to Paris Hilton to Mandy Moore, the economy has influenced consumers to pull back and celebrity lines are suffering. However, celebs like Gwen Stefani with her L.A.M.B. line, and Justin Timberlake with his William Rast line, have remained successful. Others in that category include Mary-Kate and Ashley Olsen’s The Row and Elizabeth and James brands, Nelly’s Apple Bottoms jeans and Beyoncé Knowles’ Deréon label.

However, celeb Mandy Moore has closed her t-shirt label, while Paris Hilton is seeking a new apparel licensee since her Dollhouse jeans run proved rather unsuccessful. Anchor Blue also canceled Heidi Montag-Pratt’s “Heidiwood” line after just one year, while Lauren Conrad closed her sportswear line but is now in works with Kohl’s to do an inexpensive line. And don’t forget J. Lo – she closed her Sweetface line along with her J. Lo by Jennifer Lopez apparel line.

With all the celebs jumping on the fashion designer bandwagon, these lines have quickly lost their appeal, aside from a few who have designer quality products like William Rast and L.A.M.B. Experts are saying that another reason brands such as these have been successful is because these celebs have a bit of humility, and their names are not part of the brand name. Apparently this trend isn’t affecting Miley Cyrus, who is in the works with Max Azria on a line for Wal-Mart. Beyoncé is also launching a new label called Sasha Fierce.
