Islam enjoins both men and women to dress modestly. Muslim women are expected to cover their heads and wear long-sleeve garments that reach from the neck to the ankle. Beyond these general conventions observed by all, Muslim female costume has always varied greatly from culture to culture and from period to period in terms of textiles, design, layering of garments, the style of headdress and accessories. Social class and ethnic background have also played a role in a woman’s appearance.
