Wigmakers Petitioned King "to Make Wig-Wearing by Males Compulsory"
(p. 384) . . . , pretty abruptly, wigs went out of fashion. Wigmakers, in desperation, petitioned George III to make wig-wearing by males compulsory, but the king declined. By the early 1800s nobody wanted them and old wigs were commonly used as dust mops. Today they survive only in certain courtrooms in Britain and the Commonwealth. Judicial wigs these days are made of horsehair and cost about £600,
I'm told. To avoid a look of newness - which many lawyers fear might suggest inexperience - new wigs are customarily soaked in tea to give them a suitable air of age.
