I'm going to give fashion advice on the first date.
Why would you? Did they ask for advice?
No, but I'm not going to put up with someone who has a bad fashion sense.
Even if you think you're helping, giving someone advice on the first date without them asking is not a good idea. It will make you come off as very judgmental and will make your date not like you. You should be polite and respectful on your first date.
Who asked you anyways, nobody cares.
That's kind of hypocritical. They didn't ask for your fashion advice either.
