Pattern piece #5 is the godet.
The lingerie fabric I am using as a test muslin is very unusual “lingerie” fabric. I think it is used more for skating costumes. It is brushed on one side so the stitches of the knit are invisible. I turned it over and eye-balled the grain as I ran a machine basting stitch the full length of the 3 yards so I could try to cut on grain. Difficult!
