I knew there must be a reason why Katie Holmes had been seen wearing so much denim recently – apparently she is soon to join the long list of celebs turned denim designers. Star Magazine have reported a source as telling them “she’s designed four prototypes and hopes to debut her collection at Neiman Marcus.” She has certainly been doing her homework, in the last month or two she has been photographed wearing jeans by J Brand, PRPS, Current/Elliott and Tsubi.
