There are several types of robes worn by various denominations and religions. For example, a cassock is a tight-fitting ankle-length robe worn by Catholic priests and others in religious orders. The Anglican tradition has several types of robes, including the surplice, which is a loose-fitting white garment that is worn during services. Other common synonyms for an ecclesiastical robe include vestment, habit, gown, and cassock-alb. These words all refer to different types of garments worn by members of the clergy or religious orders.
