An ecclesiastical garment worn for church services; also, coverings for the altar.
Special apparel worn in the conduct of religious services. The celebrant's Eucharistic vestment consists of the amice, alb, cincture, stole, maniple, and chasuble; a priest's or deacon's choir vestment consists of surplice, hood, and scarf. Often, each item of ecclesiastical apparel is called "a vestment." The cassock is not, strictly speaking, a vestment.

Garments (robes and gowns) worn by Ecclesiastic officials and their assistants. A vestry is a room in a church where sacred vessels are kept and where clergy put on their vestments (sacristy); in the Anglican and Episcopal Churches, a vestry is a group of members who manage the temoral affairs of the church. A vestiary is a supply room for clothing in a monastery.
An article of clothing worn over street clothes by those officiating or assisting at liturgical celebrations.
Vestments are liturgical garments and articles associated primarily with the Christian religions, especially the Catholic, Eastern Orthodox, Methodists, Lutheran and Anglican Churches. Many other Protestant groups also make use of vestments, but this was a point of controversy in the Protestant Reformation and sometimes since - notably during the Ritualist controversies in England in the 19th century.
