The stola was a long, pleated dress, worn over a tunic (the tunica intima, the Roman version of a slip). A stola had long sleeves, but the sleeves could either be a part of the stola itself, or part of the tunic. The stola was typically girt with ribbons. It was frequently accompanied by a long shawl-like garment called a palla.
