I think we can agree that the event as a whole is what calls for a mode of dress, and that we usually just dress the way everyone else does. I don’t think we need to disagree on that.
I am simply suggesting that the level of dress for girls on a first date should be higher than it is now. That’s all. So if it was considered normal, it would be that way. I don’t think you would look ridiculous dressing up on a date, any more than you do wearing a shabbos outfit to a starbucks.
Especially as some posters agreed that girls dress up for weddings to be noticed.
I recall once on a date the girl pointed out another couple where the girl was very dressed up. I wondered to myself why she was not dressed up as well.
I would have appreciated it. I bet most guys also would. I shined my shoes, and shaved and wore my best suit and nicest tie. I dressed far better than I do for a wedding. I did it for you. Do something for me.
