Sir Paul McCartney's fashion designer daughter STELLA has slammed the fashion industry for continuing to use animal fur in new designs. Sales of fur products have just hit $965 million (GBP500 million) for the first time - a rise of 30 per cent in two years - and stars like Keira Knightley, Nicole Richie and Kate Moss have all been snapped wearing fur recently. MCCartney is furious fellow designers like JEAN-PAUL GAULTIER, JULIEN MACDONALD and Alexander McQueen are continuing to stage catwalk shows with real fur. The 35-year-old designer and animal rights campaigner fumes, "There's nothing fashionable about a dead animal that has been cruelly killed just because some people think it looks cool to wear. The continuing use of fur is a real problem in the fashion industry. "There is an issue with people out there assuming that fur trim is fake when most of it is real."
