This is a modified pattern from A Very Easy Vogue.
I found a heavy rayon upholstery fabric that looked good right and wrong side, so I didn't want to line it. It has a heavy, silk like drape. So I assembled the whole thing on a serger using a 3-thread roll stitch to give me finished seams and edges.
I extended the collar to a three button up scarf that sits inside of the hood. I used more upholstery cord trim, in two weights, to give all the edges a more lux look and to give it a weightier hang.
I was careful to cut the fabric so that the pattern would be symmetric.
