Shown above is a billboard in New York, urging  youth to pull up their pants.  Senator Eric Adams of New York, spent his own money for the billboard because of  his strong feelings about this dress style in his Brooklyn district. 
  Many do not understand the style since it is a hinderance when one is walking and it sends an undesirable message regarding personality.  So do you really want to stand out in a negative way?  The sign is placed to give hope that the low pant wearers will raise their pants and  therefore their image.
