PT, you're in the house. You can take the hat off, already.
Jer, take it from one who knows. Only wannabees wear suits. A real tech wears slacks and a shirt with the sleeves rolled up. Never a tie, and forget a jacket. Any jacket worth wearing is gonna be wool, or silk. Both are a bitch for static. Ties drop into machines, and are only for comic relief. Sleeves rolled up makes you look like you're not here to waste any time. Clean shaved makes you look younger. You wanna look like you've seen/done it all. I've started to let my hair grow longer too. If anyone comments, I reply, "I'm too good a tech for my boss to care about my hair".
The customers take one look at me and recognise that fact. If the bosses are bringing me to a meeting with clients ... i'm that damn good.
I've heard it called reverse image.
