Albs are a type of vestment worn by priests during religious ceremonies. They are white, full-length garments that reach the feet and have long sleeves. Albs are usually made of linen or cotton and are often decorated with embroidery or lace. Altar vestments are special garments worn by priests when they are officiating at the altar. They are typically more ornate than albs and may include chasubles, stoles, and maniples.
