(the listener's or a third party's) daughter (polite)
Polite form for someone else's daughter: 娘 plus the honorific suffix さん. One's own daughter, to outsiders, is 娘 without さん. お嬢さん is the more refined alternative.
Congratulations on your daughter's marriage.
Polite reference form for another person's daughter: 娘 + さん. Do not use it for your own daughter when speaking to outsiders.
