Popa bar Abba, what is the purpose of wearing perfume on a date? The man is not allowed to smell it as she is an erva.
A man is generally not allowed to gaze at any part of any erva woman for pleasure.
So what is the point of her dressing up at all? Or even going on the date at all?
I don’t know. But she should dress up, and she should wear perfume. I don’t know the sources on this, but I know this is what my rebbeim say.
So don’t trust me, ask your rav.
