In Judaism, nudity is an aspect of body modesty which is regarded as very important in most social and familial situations. Attitudes to modesty vary between the different movements within Judaism as well as between communities within each movement. In more strict (orthodox) communities, modesty is an aspect of Tzniut which generally has detailed rules of what is appropriate behaviour. Conservative and Reform Judaism generally promote modesty values but do not regard the strict Tzniut rules as binding, with each person being permitted (at least in principle) to set their own standards. With the exception of the Haredi community, Jewish communities generally tend to dress according to the standards of the society in which they find themselves.
