Does nudism mean complete nakedness

Answer 1

Nudism is another word of saying naked. People these days clarify nudism as nude whether or not wearing knickers or a bra it does not make a different whether you are showing your full body or just your stomach.

Another view:

Nudism is the practice of being nude in mixed company. Many people practice this as a lifestyle, meaning they spend a significant portion of their lives nude around many other people. In essence, you could say that nudism is tied directly into the state of being naked. However, most nudists live by a phrase that reads similar to "nude when possible, clothed when practical," which means that when there is a good reason to be clothed (such as cold weather, dangerous work, etc.), then they will be.
