Tunic. A garment of high antiquity, now only worn by women and boys, but amongst the Romans and Greeks common to both sexes. Generally speaking, the tunic of the Romans and Saxons was a close-fitting garment reaching below the knees, enveloping the whole body, and fitted with sleeves. The Romans, who did not begin the wearing of tunics until a late period, soon wore them in duplicate, the under tunic being called by them the subercula, and the upper, distingushed by bands denoting the rank of the wearer, the indnsium. Through them it was introduced into England, and soon became the ordinary wear of the natives, continuing in use under a wide variety of lengths and forms until the 15th century, after which time it is, as an upper garment, lost sight of.
