Roman clothing was a system of social communication before it was a system of warmth or modesty. What a Roman wore told every observer who saw them something specific about their legal status, their social rank, their occupation, their marital status, and the occasion they were attending. The reading of clothing was automatic and precise in a society that had neither name tags nor business cards and that organized its social interactions around the rapid assessment of social position. Dress was not merely decorative; it was informational, and the information it carried was regulated by law and custom with a specificity that modern dress codes do not approach.
