I'm starting a new job in Scottsdale, Arizona where the summer temperatures are 110+. This is an engineering profession where fashion is usually Dockers and Polo shirts. Like it or not, that's the way it is for engineers, in the summer, in Arizona. That being said, I don't necessarily want to follow that "trend", but showing up to work in a long sleeve shirt and tie in the Arizona summer would land me a session with a counselor. I'm looking for suggestions on shirts and/or slacks. I want to look fashionable and nicely dressed without looking like I'm out of place. Engineers have a reputation of being geeky dressed nerds, and it is a reputation that is deserved. I would like to look better than that. I should mention that I am 45 and this is a Senior level engineering position where I will be directing others. However, even the upper management folks do not wear ties. It is what it is, I can't change that. Any help is greatly appreciated.
