I would probably do what you do if it were a situation I found myself confronting. No problem being a guy in a white shirt and pants.
I see where the bit that you bolded could have been misinterpreted.
If you're going to wear the uniform, wear it properly. Don't walk through the airport with your top button undone, or your tie off, or whatever other amateur combination you come up with.
