Custom outfit: vouivre, split-color hair, black hair, blonde hair, hair pulled back, long hair, two-tone skin, red skin, white skin, pointy ear, yellow eyes, colored sclera, mismatched pupils, monster girl
Use this as a starting point, you can try adding her wing back in but it is pretty unstable, it's easiest to leave it out when changing outfits.
