This jacket is a jack-of-all=trades.  It is somewhat dressy, somewhat casual, somewhat sporty, somewhat feminine, somewhat tough...everything you could want from a jacket.  The jersey is heavy enough to keep you warm in even in the 50's, but not too heavy that it feels like it is pulling on the back of your neck and shoulders.  I actually wore it as a long "dress" over leggings with boots.  Sure, my mom asked if I planned to take off my jacket, but when I told her it was my shirt for the day, she smiled and said, "That's a great shirt-dress, looks comfy."  It is comfy.  I'm glad I purchased it.  Great job prAna!
