I think appearance is important, however I think there are lots of shades of grey when it comes to what is deemed "appropriate." I was at a job fair and met this guy who rode his bike to the job fair. Very green of him, right? Well he was wearing what used to be khaki pants, now khaki cut-offs, and a neon colored T-shirt. He was sweating, a lot. His appearance...not so good. I am not entirely convinced hose vs. no hose is going to get you a job. If you look professional, then you are in the running. Sidenote: I have a tattoo on the top of my foot, and I begin working at a Catholic school in August. The P has already told me that the parish priest wants teachers to dress business-casual (not suits, but a bit more formal than any school I experienced). Hose, as told by the AP, were a matter of choice, because she fought and won that battle. I look forward to 100 degree days and hose, in order to somewhat cover my tattoo!
