A society's attitude to public nudity varies depending on the culture, time, location and context of an activity.
There are many exceptions and particular circumstances in which nudity is tolerated, accepted or even encouraged in public spaces.
Arousal is most evidently indicated by the sex organs and women's breasts, which are routinely covered, even when other parts of the body may be freely uncovered.
Yet the nudity taboo may have meanings deeper than the immediate possibility of sexual arousal, for example, in the cumulative weight of tradition and habit.
Clothing also expresses and symbolizes authority, and more general norms and values besides those of a sexual nature.
