Standards of modesty discourage or forbid exposure of parts of the body, varying between societies, which may include areas of skin, the hair, undergarments, and intimate parts. The standards may also require obscuring the shape of the body or parts of it by wearing non-form-fitting clothing. There are also customs regarding the changing of clothes (such as on a beach with no enclosed facilities), and the closing or locking of the door when changing or taking a shower.
