H&M is expecting a serious rush when it unveils its one-off collection by Stella McCartney on November 10, not least because Kate Moss will be the face of it. The collection, preceded by a similar project by Karl Lagerfeld last season that caused shopping chaos in and outside H&M stores worldwide, comprises 30 pieces and will go on sale at approximately 400 stores across 22 countries. Shot by Mario Sorrenti, Kate, who wears a limited-edition hand-embroidered jacket for the campaign, will appear in print ads in Europe and across America. "This one-off collection is a 'best of' Stella McCartney," says Stella. "So many people come up to me and say 'I love your designs but could never afford them'. This collaboration is a great way to speak to a wider audience and let them get to know me and my designs better."
