Well, this is about the closest pattern I could find...
http://sew-n-sewpatterns.mybisi.com/product/butterick-4666-ladies-fleece-ponchocapejacket-patternIt's out of print, but it looks like there's still places around to order it. You could just make the tan view on the top left. All you would have to do to make it like the one in your picture is make the lapel a little wider and rounder, overlap it a little more to make it double breasted, and put in bound holes right about where your elbows would fall. It looks like the model in the picture has it belted around the front and then through those arm holes. Hope that helps!
