80% of my clothes are sportwears for a long time. It gives the feeling that you are a pro. A professional athlete, and a professional at your career, your performance totally relies on you.

Nothing looks more professional than someone sitting at a desk in yoga pants or a tracksuit. Yes indeed.

You know what else looks professional? A military or public services uniform. This guy should get a firefighter outfit to wear while sitting at a desk typing code. Then he'll feel really professional.

I'd go for the blue jumpsuit. Throw in a couple of spanners for good measure.

I prefer the professionalism of black leather, myself. Sure, it creaks a little when I move and gets a lil sweaty in hot weather but at least it doesn't smell as much as latex.
