I whipped this together real quick for my daughter for Halloween, but I am hoping she will wear it for other events like over her cotillion dresses or for Colonial dancing. She is about 5'1" tall. I bought 2 yards of a thick poly wool blend fabric (no lining). I measured down 17" from the top and gathered the full width of the fabric. I hand gathered it because I was in such a hurry, I didn't want to risk having to redo it if the thread broke. I sewed a fabric tube over the gathering to reinforce it and to act as a tie. I hemmed the bottom edge, but just left the selvages for the front edges.
I sewed the top seam to form a big, floppy hood. She loves it! I figure I can always go back and line it later if I want to. It survived Halloween and that was my main goal anyway.
