I used the same cheapy (but cute) fabric as I used on this Burda WOF skirt. BWOF says to use lightweight blouse fabrics with some body and this fabric seems to work create. My wool is a twill that had a soft hand. I think it will be perfect. I put the center band on the bias for some interest.
It is the details of BWOF that I love. This jacket has 4 pleats up top and elastic inserts in casing that give it shape in the front and back. The buttons that are on it are not the real ones. If you noticed, they are all different versions of white/bone buttons. I think I'll use a neutral bone colored button but use a bigger one. BWOF isn't any help they just say, "three large buttons."
