A dalmatic is a liturgical vestment, characterized by a long, wide-sleeved, tunic-like garment, primarily worn by deacons in Roman Catholic, Anglican, and some Lutheran and United Methodist churches. It originates from a white tunic worn in the Roman province of Dalmatia and is often decorated with colored bands called orphreys. The dalmatic's color changes with the liturgical season, and it serves as a symbol of the deacon's role as a minister of service.
