I bought this in the store totally on a whim and love it. What makes it better is that I'm pregnant and huge and this coat still rocks! For really cold days, this is a good sweater, but will be awesome for spring/fall as a coat as well. Deep pockets for all your stuff too!
Either this jacket was mislabeled, or its running a size small. Every Prana top/jacket I own is a size small, but I could barely get this buttoned. It was way too tight. In fact it was so tight, that I couldn't even gauge if the style would be flattering, so I didn't even exchange it for a medium.
