The material I ended up choosing for the coat lining is a shiny remnant with a pattern of tiny diamonds. It's probably entirely inappropriate, but the color was just what I wanted and I had barely enough. I had to piece together bits to fill out the back and still leave enough to line the skirt. The length of the skirt was determined by how much I had left over of the lining after patterning the body. As planned, I put in a pair of lacing holes on the left side that point to a ring inside the right side. The flap closes with a black thread covered button. The sleeves are wide and unlined, gathered to a small cuff.
I had to manipulate these pictures quite a bit since my lighting skills still leave much to be desired. I will happily entertain requests for any detail photos. I still have to finish the rest of the lacing holes at the waist, but other than that I can call this project finished.
