The cassock, also known as a soutane, comes in a number of styles or cuts, though no particular symbolism attaches to these. It usually has 33 buttons (symbolic of the years of the life of Jesus) down the front. There are two types of cassock: the ordinary cassock and the choir cassock. A band cincture or fascia is also worn with both types of cassocks. The ordinary cassock is the black cassock worn by most clerics. Choir dress cassocks for bishops, protonotaries apostolic, and honorary prelates are purple.
