The Roman tunica was worn by citizens and non-citizens alike; citizens, though, would wear it under the toga, especially at formal occasions. The length of the garment, the presence or lack of stripes, as well as their width and ornamentation, would indicate the wearer's status in Roman society. Soldiers, slaves and manual workers generally had tunics to a little above the knee; those in more sedentary occupations to about the ankle (unless they were expecting to ride a horse, when a shorter one would be worn).
Underneath his armor, the Roman legionary wore a (usually woollen) tunic. There is considerable debate today as to whether the typical Roman legionary's tunic was undyed or dyed red using madder dye; a number of works of art and written descriptions contemporary to the Roman Empire contradict each other on this point. Alternately, it is possible that Roman legionary officers wore red tunics, while rank-and-file soldiers wore undyed tunics.
The tunic originally worn by the Roman legionary consisted simply of a long piece of rectangular cloth sewed to an identical piece, with holes for the arms and head simply left unsewn. Later, it became fashionable for tunics to be produced with sleeves and worn with braccae. This was especially the case in relatively cold northern territories such as Britain and Germany where similar clothes were already in existence among the native populations.
Following the fall of the Roman empire, the tunic continued to be worn with varying sleeve and hem lengths throughout Europe during the Middle Ages. Often reaching the knees or ankles, it was usually worn over underclothes consisting of a shirt (usually hip-length or longer) and drawers (usually knee- or ankle-length pants related to braccae). It may be accompanied by hose. Wool and Linen were common fabrics used, though the wealthy sometimes wore fancy silk tunics, or a lesser fabric with silk trim. Tunics worn during the Early Middle Ages often featured decorative embroidery or tablet-woven braids along the neck, hem and wrists. This was the case, for instance, with tunics worn by both rich and poor Anglo-Saxons before the Norman Conquest.
