Certainly agree with GFM. I have a nice Polo covert-cloth coat in olive/brown with a mid-brown velvet collar (an Ebay steal at $250). I use it as a transitional coat - it is nice in spring-fall, through much of early fall and again in the current winter/spring transition.
Most of the coats I have seen of this type are like mine - a mid-weight cloth, and not too warm.
If you are going to Chicago, better plan on this for early fall. NYC may be a bit more forgiving, but can get pretty cold as well.
