A loosely fitted over-robe worn throughout Arabia and across North Africa. Traditionally, the abaya is black, and includes a hood to cover the hair. Often is accompanied by a matching scarf or shayla to cover the hair. There are two major styles of abaya. A closed or pullover abaya is styled much like a loose khaftan with loose sleeves. An open abaya is an unstructured garment that is folded and stitched at the tops of the sleeves, or down along the sides.
