As with most things, it’s a question of balance. You don’t want to go to one extreme or the other. I tend to see more of the “extreme modesty” side since I attend the latin Mass. One woman even comes dressed in what I can only call a burka! It’s one thing to be modest, quite another to deliberately make yourself unattractive. After all, caring about the beautiful (in art, dress, etc) is one of the best qualities in women.
