As the weather in the windy city changes from moderate to cool and crisp, so do the clothing choices. Out of necessity women are wearing coats, scarves and boots. The variation of coats I have been seeing on the streets are both numerous and so chic. Heavy cotton blazers, leather jackets and military trenches are among the many styles of the season. Celebrities, such as Blake Lively, have mastered the art of fall fashion, and it seems Chicago women have taken note.  It is easy to get lost under the layers of cold weather, but these ladies have figured out how to use outerwear in a fashionable and practical way.
