I deliberately wear ironed white business shirts, linen pants and even a tie to my programming jobs. I like to mess with my co-workers heads. This went on until one day the boss walked out (wearing a ripped T and no shoes) and told me to stop wearing business shirts. He also declared the programmers area a no-shoe zone and ordered us to print out some pornography and put it on the walls. As it turned out he was joking about the pornography.
However when I'm not programming I prefer comfortable clothing and have been reprimanded for letting my standards slip too far.
I didn't believe in evil until I dated it.
