Trousers: In the early 19th century, trousers were sewn with a flap in front called a fall front and was held in place by two or three buttons. Trousers were held up by tight-fitting waists which were adjusted by gusset ties in back of the waist. Seats were baggy to allow a man to rise comfortably from a sitting position.
