At the end of the service some persons kneel for a private prayer before leaving. Vestments To add to the beauty and festivity of the services, and to signify their special ministries, the clergy and other ministers wear vestments. Choir vestments usually consist of a surplice. The clergy may also wear cassock and surplice. Another familiar vestment is the alb, a white tunic with sleeves that covers the body from neck to ankles.
Deacons wear the stole over one shoulder, priests and bishops over both shoulders.
The deacon's corresponding vestment has sleeves and is called a dalmatic. Bishops sometimes wear a special headcovering called a mitre. Stoles, chasubles, and dalmatics, as well as altar coverings, are usually made of rich fabrics. Their color changes with the seasons and holy days of the Church Year. The most frequently used colors are white, red, violet, and green.
