אל תחלל את בתך להזנותה ולא תזנה הארץ ומלאה הארץ זמה
Do not profane you daughter to lead her astray, so that the land should not be led astray and filled with sexual immorality
The Ohr HaChaim comments:
G-d commands us that one who has a daughter should not conduct her in a profane manner to display her before everyone and to beautify her before them, but "the glory of a princess is inward". Even if he intends this for the sake of marrying her off, in order that it should be known that she is a beautiful girl and pleasant, so that she should be married to one who is worthy of her, despite this God commands us that this is a profanation of her, and what will come of this is to lead her astray, not to marry her off, for the natural fire will burn inside her and her honor will be profaned. Not only this, but this will cause the fire to burn inside the heart of those who see and desire her, and the land will be led astray, and in the end the land will be full of immorality. It will turn out that the sin of all the evil will hang from his neck...
