This is one of my favorite visions of the character Death in the Sandman series so far. She comes from the story "The Heart of a Star" in Endless Nights...Death before she 'cheered up.'
Once I have the sketch scanned in, it'll be easier to see how this costume will be made. It's got sort of a tailored Renaissance look, same as the rest of the Endless siblings in this story. (Dream's tailored highwayman's jacket with black-and-white slash sleeves is high on my 'to-make' list.) Death's gown is a plum-violet underdress with a standing collar and sort of mutton-chop sleeves at the shoulders with a black v-neck tunic, waist cincher, and "sleeves." As usual, the hardest part is going to be finding a good black wig.
