And tell the believing women to restrain their looks (also in the presence of men who are not near of kin and so lawful for marriage) and guard their chastity and not to disclose their (natural and make-up) beauty except such as cannot be helped (and is apparent) and draw their head coverings over their bosoms, and they should not display their beauty save to their husbands or to their fathers or to their fathers- in-law or to their own sons or to the sons of their husbands or to their own brothers, or to the sons of their brothers or to the sons of their sisters or their women (who are their decent companions) or to their bondsmen or to such of their male attendants as have no sexual appetite or to such young children as have yet no knowledge of the frailties of women. And let them not strike (the ground with) their feet so that which they (must) hide of their beauty or adornment) may become known. And (O believers!) turn to Allâh; one and all, that you may attain (true happiness and) your ultimate goal. - Quran 24:31
