A cassock is a long, robe-like garment worn by clergy members in various Christian denominations. Typically made of black or other dark colors, it serves as a symbol of the wearer's religious commitment and authority. The cassock is often worn during religious services, ceremonies, and other formal occasions. In addition to its traditional use, the cassock can also be associated with specific roles within the church, such as priests, deacons, and bishops. It may be paired with other vestments, like the stole or chasuble, depending on the occasion and the denomination's customs.
