Chlamys
Chlamys, a short, light mantle in use among the ancient Greeks, and adopted to some extent by the Romans. In form it had three straight sides, and one curved, and was generally arranged with the two squared sides brought together on the shoulder and fastened by a brooch. Ancient statues and carvings show many different modes of letting the folds hang.
