Nude swimming or skinny dipping is the practice of swimming naked, originally in natural bodies of water, but more recently in swimming pools or hot tubs. The widespread social convention and practice today is for swimmers especially in public places to wear a swimsuit. Most countries do not have specific laws proscribing nude swimming, and the matter is regulated largely by social convention and practice. Most nude swimming today takes place on nude beaches, or at naturist facilities, segregated public swimming areas or in private swimming pools. Some countries around the world regard nude swimming as public nudity, which is treated in a variety of ways, ranging from tolerance to strict enforcement of prohibitions against it.
