Q: What is an under stole? How is it worn?
A: An under stole is just a stole. At mass the priest usually wears a stole over his alb and under his chasuble. However, after the council, some priests started wearing their stole over the chasuble. It varied the traditional design, lent some visual interest, and helped distinguish the priest from the deacon more visibly than the chasuble and dalmatic do. Even popes have worn a stole over the chasuble on occasion. However, the GIRM indicates that the stole is worn beneath the chasuble. You sometimes hear references to “over stole” and “under stole”, but those expressions simply refer to two different ways of wearing the same stole.
