women like to dress up very beautiful, even sexy, and makeup their
hair, then they cover themselves up and go to a party in which only
women are present. Is this allowed?
they like to do that, and they are careful not to be seen by strange
men (ghayr mahram) with such adornment, and their travel
to the party is not observed (i.e. their makeup and dresses are
well-covered by outer garments), and no men are present at the party,
even if they are uncovered that is permitted.
