Chador

A chador is a full-body-length semicircle of fabric that is open down the front. This cloth is tossed over the woman's or girl's head, but then she holds it closed in the front. The chador has no hand openings, or any buttons, clasps, etc., but rather, it is held closed by her hands or tucked under the wearer's arms. Before the 1978–1979 Iranian Revolution, black chadors were reserved for funerals and periods of mourning. Light, printed fabrics were the norm for everyday wear. Currently, the majority of Iranian women who wear the chador use the black version outside, and reserve light-coloured chadors for indoor use.source:wikipeida
