 Shaped like the body coats popular in the late Victorian and Edwardian periods, the over-frock coat was cut in essentially the same way as the frock coat that was worn under it, although it would be larger overall to accommodate the frock-coat worn underneath.Like the frock coat, the over-frock would typically be single-breasted, with step lapels for informal occasions like business, and double-breasted with pointed lapels for formal occasions - weddings, funerals, balls, etc.The formal variety was sometimes called a "Prince Albert overcoat".
