I heard from someone that the girls in the times of the gemara wore make-up and I think it was encouraged so if they could, we can. There’s a difference between attractING and attractIVE. Some might look like they’re dressed for their wedding but there’s nothing wrong with looking super-good if it doesn’t scream out (most girls don’t). It’s the natural thing for a girl to want to look pretty. There is NOTHING wrong with H.S. girls wearing make-up to a normal degree. As for married women, I can’t speak because I’m not married.
Everyone complains about the levels of tznius nowadays and the worst is usually in H.S. but I’m there and IMHO, girls are burnt out of these speeches. Teach more about middos and sincerity in yiddishkeit and hopefully tznius will seep in too.
