I have to say that I have some workwear pieces, and often use them in settings that would traditionally be considered "appropriate" for work wear i.e. in the machine shop on campus, welding, working on cars etc. I'm probably also the only mechanical engineering student at Montana State that cares somewhat about fashion, so I wear these things primarily for myself. I say wear what you like, it's not like one has to be relegated to one aesthetic for their entire wardrobe. I pretty much wear prep/trad stuff all summer long. 2 cents.
