I made this for our Katsucon skit, the only part I used from the old costume is the boots. Most was purchased (hoisery, garters, skirt) but I did sew the corset from scratch. It's 3 layers- a black cotton, sheer skull print and lace overlay. It's fully boned, and laces up the back with a black / silver ribbon that I also used for straps. I cut the lace fabric to make a trim, and sewed on black swarovski crystals to give it some oomph from the stage.
The wig was purchased on e-bay from cosplaywigs, I added the pigtails. The boots are from cosworx, and they're fantastic.
