Surplice
The surplice is a loose-fitting white liturgical vestment worn by clergy and choir members in many Western Christian churches. It is typically worn over an alb or cassock. The surplice is usually shorter than an alb, often knee-length or shorter, with short or wide sleeves; many examples feature lace or embroidery at the cuffs, yoke, or front. Styles vary by tradition: in Catholic and Anglican usage the garment may be plain or heavily trimmed; longer forms are sometimes worn for solemn services, especially by choir members.
Usage and function: In the Catholic Church, the surplice is worn by priests, deacons, and altar servers
Origin and relation to other garments: The garment originated in the medieval period as an overgarment worn
