Wearing your jeans so low that your underwear shows was, for a long time, the privilege of fat builders whose ample belly forced the jeans down and, as a result, also exposed part of their butt. Then came baggy jeans and the skateboarder movement, whose garb made a fashion trend out of the extremely low waistline. A new commercial for Keler brand beer rewrites fashion history by claiming that the trend accidentally came into being when a guy at a bar stuffed a couple of bottles of Keler into his front pockets to have his hands free for another two bottles, which he carried from the bar to the table his friends were sitting at.
