The ALB is a white, ankle-length robe worn by priests and other ministers of the Catholic Church. It is usually made of linen or cotton and is often decorated with embroidery. The ALB is typically worn with a stole, which is a long, narrow band of cloth that hangs around the neck and is used to signify the priest's office. The ALB is an important part of the priestly vestments and is a symbol of purity and holiness.
