Cassock
A long, close-fitting garment with narrow sleeves worn by clergy and other ministers. Cassocks are typically black but also may be blue, gray, or red. Bishops may wear purple cassocks. It may be worn under a surplice. Historically, the cassock was the street garb of a person in clerical orders. It was part of the outdoor dress of Anglican clergy until the beginning of the nineteenth century.
