The men wore a tunic underneath a toga, which [the latter] had different stripes on resembling their status in society and job. They could wear sandals or boots.

Women wore a stola, which was like a full, flowing dress, a palla [originally from Greece] worn as a head-scarf or belt. Sandals or boots were worn on the feet. At one time prostitutes had to wear a toga to distinguish them from other respectable women.

Children would wear tunics and a bulla [a necklace that indicated that they were free-born]. They would wear sandals or boots too.
