This character wears a veil.
A veil is an article of clothing, worn almost exclusively by women, that is intended to cover some part of the head or face.
One view is that as a religious item, it is intended to show honor to an object or space. The actual sociocultural, psychological, and sociosexual functions of veils have not been studied extensively but most likely include the maintenance of social distance and the communication of social status and cultural identity. In Islamic society, various forms of the veil have been adopted from the Arab culture in which Islam arose.
