For her newest designer collaboration, Kate Moss, who has already added her signature to collections from Rimmel, Longchamp and Topshop, graduated from just receiving prank calls on her smartphone to designing accessories for them. Today, the UK’s high-street phone store, Carphone Warehouse, announced the Kate Moss Accessories Collection, a line of signature covers for phones and tablets for the “fashion conscious” tech user. “My phone’s as much a part of my look as my bag or my shoes, and yet there’s so little choice out there,” said Moss, who plans to design two collections a year. The first will be available in stores and online later this summer. And this isn’t even her most unexpected collaboration. Remember the $58 Kate Moss-designed sushi box?
