Soon-to-be graduate here. I'll be starting work this summer at an engineering and manufacturing form in New York state, and I'm trying to figure out what kind of work wardrobe to put together. The dress code is business casual, which I understand. The issue is that I will inevitably be spending time going out into the shop to inspect parts, build prototypes, and that kind of thing, and I don't want to be constantly getting grease/soot/etc. on nice clothes. For all you engineers on SF, what do you do about this? Do you wear (relatively) inexpensive clothes to work?
