[fidelis]

If I dressed in a feminine suit and was careful with hair and makeup, I would often be upgraded to first class when I checked in at the ticket counter.

That works for men too. I've noticed than when I'm wearing a suit and a tie, people in general are nicer, and even a little more deferential to me. Get a lot more smiles from women, too, especially those of a mature age.

I don’t wear suits, but I notice that when I go to the local market the cashiers are really nice and will even say hello when I’m wearing yard work clothes. The same people are jerks when I have on my engineer-wear of Pakistan and golf shirt.
