Whatever happened to the perfectly good term 'fancy dress'? I suppose one might argue that 'cosplay' emphasises the element of play to it, of playing the role the costume suggests. One such man who loves to do this is Justin Trudeau. There is nothing terribly wrong with that - except that he does it when representing the country he is prime minister of on the world stage. Even worse, the majority of Canadians seem to think this is perfectly normal.
