"In most businesses if a man wears anything except a suit and tie it is a topic of serious consideration, and possibly a firing offense."
I don't know if that's as true as it used to be. Business casual has pretty much taken over most of corporate America by now. True, you might not be able to roll into work at a non-tech Fortune 500 company wearing a hoodie and jeans -- but you aren't expected to wear a suit, generally speaking, unless you're in the C-suite or in a high-profile, externally facing role (investor relations, BD/CD, etc.).
Suits are generally relegated to the professions these days: big law firms, banks, and what have you. I'm sure there's the occasional company (F500 or otherwise) that mandates suits for cultural or traditional reasons, but such a company is likelier to be the exception than the rule in 2016.
