In this use, it may be considered inappropriate or immodest to reveal certain parts of the body. In some societies, modesty may involve women covering their bodies completely and not talking to men who are not immediate family members; in others, a fairly revealing but one-piece bathing costume is considered modest while other women wear bikinis. In some countries, exposure of the body in breach of community standards of modesty is also considered to be public indecency, and public nudity is generally illegal in most of the world and regarded as indecent exposure.
