The solid black exterior has no zipper or slits, with floor-length mini train and sheer gray cape. She wears black patent stiletto pumps with bare legs, standing at a night party with hands together and gentle smile. Viewed from above, she has her signature pink hair in a side tail with bow, fang visible, and pink eyes. The composition emphasizes the luxurious satin texture and elegant silhouette of the gown against the nighttime setting.
