I went back in time and farted on a puppy. Sorry. You really should have seen the original timeline. We had blimps, universal healthcare, and six seasons of Firefly
Anyway, I was thinking less 'european aristocrat' and more 'steampunk aesthetics' when I talked about vests. Dress shirt, tie, vest, and overcoat, all slightly stained with oil from physically impossible doohickeys full of gears. T'is a nice aesthetic.
