It's made from plum wool, with a tan pinstripe, I got it on clearance at Joann's for $1.88/yd, and the neckline is trimmed with some gold tone changable silk I had laying around.
The cut of this dress is probably not 100% accurate, but all of the really major "sins" are cover by the apron dress. All of the gores make the skirt wildly full, but didn't really chew up all that much fabric - I love rectangular construction.
