Liturgical robes, also known as albs (4 letters), are garments worn by clergy and other church officials during religious services. They are typically white and made of linen or cotton, and may be decorated with embroidery or other symbols. Albs are often worn with a stole, which is a long, narrow band of fabric draped around the neck and shoulders. The alb is a symbol of purity and holiness, and is an important part of liturgical worship.
