A yashmak, yashmac or yasmak (from Turkishyaşmak, "a veil") is a Turkish type of veil or niqab worn by some Muslim women to cover their faces in public. Today there is almost no usage of this garment in Turkey. Veil is a Persian custom adopted by Arabs.
Unlike an ordinary veil, a yashmak contains a head-veil and a face-veil in one, thus consisting of two pieces of fine muslin, one tied across the face under the nose, and the other tied across the forehead draping the head.
A yashmak can also include a rectangle of woven black horsehair attached close to the temples and sloping down like an awning to cover the face, called peçe, or it can be a veil covered with pieces of lace, having slits for the eyes, tied behind the head by strings and sometimes supported over the nose by a small piece of gold.
