Surviving stays, or corsets as they became to be called in the nineteenth century, show that both longline and shorter corsets were worn and that they were made of cotton, silk and sateen. A lot of these corsets were front fastening, plus many were laced at both the front and the back so our aristocratic fictional heroines could indeed dress and undress themselves without the assistance of a maid.
