The custom of people in Hong Kong's courts donning wigs dates back to the days when the city-state was still a British colony. Wigs were traditionally worn by judges as a mark of their power and to set them apart from the general populace. The wearing of a wig was considered to be an indication of one's deference to the established order of things as well as a sign of authority and distinction.
