Garments cut like the traditional kameez are known in many cultures; according to Dorothy Burnham, of the Royal Ontario Museum, the "seamless shirt," woven in one piece on warp-weighted looms, was superseded in early Roman times by cloth woven on vertical looms and carefully pieced so as not to waste any cloth. 10th century cotton shirts recovered from the Egyptian desert are cut much like the traditional kameez or the contemporary Egyptian jellabah or galabia.
Salwar kameez dates back to the 12th century, the Islamic or the Iranian era, which was then followed by the Mughal empire in the region now called Punjab
