What is a clerical robe called?

Clerical Robes are formal dresses worn by members of the clergy in Christianity, Judaism, and Islam. The robe is similar in form to a cassock but is much simpler.
The calrical robe begins at the top of the wearer’s chest, where it fastens around his or her neck with a cross-shaped buckle that fastens with a strap. Then it falls to mid-thigh, where it has long sleeves with bands of material at their outer edges and gathers in gores up the front. The lower part of the robe must be opaque black and extend to below the knees; this part may also be decorated with lace or embroidery. A clerical cap usually covers all or most of the head except for the eyes, nose, mouth, and ear holes for hearing.
A clerical robe is something that public sector employees wear, such as those associated with an office.
Clerical Robes are typically referred to as a covering for the body, worn by those in white-collar service occupations. They are generally made of fabric and can vary from plain dark clothing to various brightly colored garments that adorn public sector employees.
