An over-frock coat is a formal overcoat designed to be worn over a frock coat if needed in cold weather. A top-frock coat may also be worn over a frock coat in milder weather. Shaped like the body coats popular in the 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 top-frock was usually double breasted. The formal variety was sometimes called a Prince Albert overcoat. The Prince Albert top frock, from the later half of the 19th century, originally had a three-inch-wide velvet collar, and flap pockets at the hip, until 1893, when it became even more fitted, longer, and double-breasted.
