Naturism and nudism
See also: Naturism and List of social nudity places
Naturism (or nudism) is a cultural and political movement practising, advocating and defending nudity in private and in public. It is also a lifestyle based on personal, family and/or social nudity.
Naturists reject contemporary standards of modesty which discourage personal, family and social nudity, and seek to create a social environment where people feel comfortable in the company of nude people, and being seen nude, either just by other nudists, or also by the general public.
