As the daughter and sister of Anglican clergymen, Jane Austen was intimately familiar with the rites, rules and habits of church ministers. Clergy members and their families were among her closest friends and feature strongly in all her novels.
What, however would a clergyman of her time have worn?
Portraits of the era give a good idea of what they would have had in their closet:
The well dressed Clergyman, then, would have dressed somberly, in a black suit, with with stock or cravat. Over this, while preaching, he would have worn the black Cassock, mandatory to his office. Many clergy chose to augment this sober attire with white bands, also known as Geneva bands (named for the birthplace of the reformation). Additionally, while performing some sacraments, such as weddings, baptisms and funerals he might add a white surplice (hence the fee paid for such services was called a “surplice fee”.)
