I am trying to pick up a few pieces every month so "when" I start teaching I won't have such an added cost of trying to come up with a wardrobe. I will be in a h.s. science class (Chemistry, maybe biology). Are dresses realistic? Should I focus more on buying slacks and a few versatile tops? What about shoes? I would imagine stilettos are out, but then again, what do I know. Also, where is your favorite place to shop?
