The office i work in is a dress shirt, tie and slacks kinda place. The only folks you see wandering around in suits are guests and project managers. I'm pretty comfortable in this environment but feel like wearing something a bit smarter when getting called into an important meeting. I've been told the easiest way to handle this is to keep a sports coat at work. Put it on on the way to the meeting and you always look sharp. Predominantly I wear khaki, brown, linen, black and one or two blue slacks to work. Shirts are mostly white, light blue or white with windowpane patterning. So the question is: what sports coat do you keep at work? Classic blue blazer? Something in tweed? Any other suggestions?
