The classic programmer corporate power move is wearing whatever you want to the office.
Easily one of my favourite things to wear at work when the weather's good for it. Probably want to practice putting one on and keeping it secure for a bit first though - don't want it slipping off in front of people! (That would be a different kind of power move.)
It's honestly a shame that it's not socially acceptable (in the West) for men to wear skirts and dresses.
Maybe even the full historical reconstruction set I have.
