Clothing in ancient Rome
The toga was an important item and was worn by only Roman citizens, and after the second century BC, only by men. After that, the only females to wear togas were prostitutes.  The colors of togas had meaning.  A toga could be edged with purple (high rank), or be all dark for mourning.  Only emperors could wear entirely purple togas. In other words, clothing reflected status as well as practical needs.  A red lined Toga often showed shame and disgrace, often worn when banished or before an execution.
