What is an alb?

An alb is one of the basic liturgical vestments that a Catholic priest wears. It is the large plain garment made of white linen that is worn over their clothes or cassock and under other special vestments. Usually, it is worn with a belt, or cincture, around the waist.

Adopted from the long linen tunics that the ancient Romans wore, it is said to be the oldest liturgical vestment used by the early Christians. It was primarily used in the celebration of the Eucharist, but, over time, has become a common vestment used in all Christian celebrations by clergy and laypersons alike - especially priests, deacons, and alter servers.
