An apron is an outer protective garment that covers primarily the front of the body. It may be worn for hygienic reasons as well as in order to protect clothes from wear and tear.
The term "apron" also refers to an item of clerical clothing, now largely obsolete, worn by Anglican bishops and archdeacons. The clerical apron resembles a short cassock reaching just above the knee, and is coloured black for archdeacons and purple for bishops. The apron is worn with black gaiters, reaching to just below the knee, and knee-length black breeches worn with gaiters. The history behind the vesture is that it symbolically represents the mobility of bishops and archdeacons, who at one time would ride horses to visit various parts of a diocese or archdeaconry. In this sense, the apparel was much more practical than a clerical cassock would be. In latter years, this vesture was more symbolic than practical, and since the mid-twentieth century it has fallen out of favour.
