If Jesus "returned" to earth how would you recognize him?

I’d imagine that the wounds would have healed by now, and the hair was simply a style of the time so that might be different, and if he appears in a beach resort town in Europe the loincloth might go unnoticed. He was heralded for millennia before his first arrival and still only a few noticed or cared, how will anyone pick out the messiah from a crowd of billions.
