Shame dictates that the genitals should be covered even when a person is alone. The dress of women must not only cover virtually the entire body, but cannot be either transparent or close-fitting to reveal the shape of the body. When onlookers are close relations, prohibitions for women do not include hair, ears, neck, upper part of the chest, arms and legs.
In many cultures, it is considered impolite to expose one's body in public, even if alone. Women's dress codes emphasize covering most of the body, with some exceptions for hair, ears, and other exposed areas when family members are nearby.
