Hey go easy on him- it’s a bit insulting when someone shows up on a first date looking like the couldn’t be bothered to put themselves together. Unless that is her idea of being stylish, then it’s just plain rude.
(I’ve had guys show up on a first date unshaven- and after I spent 2 hours putting myself together- that is really insulting).
I agree with some of the posters above: I would talk to the shadchan – best way for the message to get across without you looking too bad and I would tell her where you are going next time…
