A lay woman who has taken special vows committing her to a religious life, otherwise known as a religious sister. They must adopt a celibate life, refraining from marriage and sexual relationships - a religious sister takes part in a religious institution, while a nun lives a cloistered monastic life. They are recognized by their distinctive set of garments, called a habit. Christian ones can be additionally recognized by the appearance of a cross or crucifix.
The term "nun" is applicable to Catholics – both eastern and western traditions – Orthodox Christians, Anglicans, Lutherans, Jains, Buddhists, and Taoists. Nuns can vary in appearance not just across each tradition, but within traditions as well; common subtypes of nuns across traditions include military nuns (or battle/combat/warrior nuns).
See traditional nun for the traditional modest Christian nun outfit, as opposed to the sexualized nun outfits typically seen in anime.
These are common among traditional nuns in set colors, but nontraditional designs may feature different things, simplified versions of the things featured here, etc. in non-standard colors.
