Side story. I once had an absolute pristine pair of vintage Chuck Taylor Converse black and white high top shoes. I was wearing them with my suit one time, and a woman goes off on a tirade on those shoes with a suit. She finishes it off with just what you you thinking wearing those #&#**$&#@(#*$ shoes with that suit. I quite calmly and politely said, it’s way too cold out for sandals.
