White linen robes, also known as albs, are a type of liturgical vestment worn by members of the clergy during religious ceremonies. They are typically white in color and made of linen, a lightweight fabric. The robes are often decorated with embroidery or other embellishments, such as crosses or symbols of the faith. Albs are usually worn over a cassock, a long garment that covers the body from the neck to the ankles. The robes are an important part of the religious tradition and are seen as a symbol of purity and holiness.
