Re: 3 piece suit
Whenever I wear a suit it's three piece - I just prefer it, find it comfortable. I have a nice lightweight pure-wool Italian one which is as cool in summer as the slacks and vest I would otherwise be wearing, snug enough in the winter.
I really don't care how people dress - from kings or queens to butt-naked - so long as they're happy and they get whatever job or task done and there's no Health & Safety issue.
Some may say I'm "too liberal" - I won't have a problem with that. I just think that if I want people to tolerate my choices I have to be willing to tolerate theirs and live by that ideal as best I can.
