any of a variety of cloth garments having sleeves and worn on the upper part of the body, often under a coat, jacket, or other garment. Shirts were worn as early as the 18th dynasty of ancient Egypt; they were made of a rectangular piece of linen, folded and sewn up the sides, with openings left for the arms and a hole cut at the fold for the head. There are also shirts preserved from ancient Egypt that have long, tight sleeves sewn into the armholes.
