Three examples of the medieval method of putting on the amice. The amice is a liturgical vestment used mainly in the Roman Catholic Church, Lutheran Church, in some Anglican churches, and Armenian and Polish National Catholic churches. It consists of a white cloth connected to two long ribbon-like attachments, by which it is fastened around the shoulders of the priest. In several Mediaeval uses, such as the Sarum Rite, the amice bore a broad stiff band of brocade or other decoration, giving the impression of a high collar. These were called apparelled amices.
