“ Poor people, who could not afford to purchase a toga, wore the tunic alone, whence we find the common people called Tunicati. A person who wore only his tunic was frequently called Nudus. Respecting the clavus latus and the clavus angustus, worn on the tunics of the senators and equites respectively, see Clavus Latus, Clavus Angustus. When a triumph was celebrated, the conqueror wore, together with an embroidered toga (Toga picta) , a flowered tunic (Tunica palmata) , also called Tunica Jovis, because it was taken from the temple of Jupiter Capitolinus. ”
