nudist
The practice of wearing little to no clothing to be "closer to nature," treating nudity as natural and nothing to be ashamed of.
This tag overlaps with (but not necessarily relates to) exhibitionism and zenra, as nudists can be naked indoors (such as the privacy of their home), as opposed to the aforementioned fetishes that emphasize public nudity and exposure to others. Nudism is usually treated as a matter of personal preference rather than deliberate titillation.
