Have you ever noticed that the best looking ones are still in first classI love when women are in uniform, not so much "authority" types but just your run of the mill outfit like a grocery cashier. The ones in the supermarket near me have to wear these tight grey pants and their asses look so cute.
My favorite though is the stewardesses for airlines like Emirates who are all fancy and beautiful. Like, put me in first class and can a few of them just pamper me? (just a dream, I can't afford it...) Whenever I fly I love looking at the attendants because they look so well put together.
As for men, business suits or sport coats, the "professional" look. If they are smart and educated all the better. A nice rugby player works too.
