It is often said that Washington, D.C., is where style goes to die. Or, as the old adage goes, that it is “Hollywood for ugly people”: a fetid swamp full of strivers, brainiacs, and nerds, nary a dandy among them. It is a supposed cesspool of sartorial sobriety. If country star Jason Aldean wrote a paean to Nashville called “Crazy Town,” someone from the DMV might just as well write a ditty about D.C. called “Frumpy Town.”
