What Is a Cassock?

A cassock is a long, close-fitting garment worn by Catholic clergy, typically reaching down to the ankles. It is one of the most traditional forms of clergy outfits and is often associated with priests, bishops and other church officials.
The cassock is worn with:
- A white clerical collar

Today, it remains an essential part of a formal mens priest outfit, especially during liturgical services and official duties.
History of the Cassock
