A more thorough explanation:

Definition: A vestry is a place in a church where the priest's robes are kept. It is also an assembly of the minister, church wardens, and parishioners to conduct church business.

Examples:

• The priest went to the vestry to get his robes before the service.
• The vestry met to discuss the budget for the upcoming year.

The first example illustrates the first part of the definition, which refers to the physical location in the church where the priest's robes are stored. The second example illustrates the second part of the definition, which refers to the group of people who meet to conduct church business.
