Need a stocking stuffer? Or just stuffer for your pants? Soccer star David Beckham and Olympic diver Matthew Mitcham are both pushing new underthings, just in time for the holidays. Becks’ wintery new H&M Bodywear collection includes cute long johns and jammies, and Mitcham’s filling out a bright new line of Funky Trunks skivvies. Can’t you picture these guys unwrapped under your tree?
