It consists of a red mini santa hat with the Cover corp logo, a red choker witn a neck bell, a short red fur-trimmed off-shoulder santa dress (although it's sometimes depicted as a strapless dress with detached sleeves), a black belt with gold chains and the buckle shaped after the Cover logo, red thighhighs and white fur-trimmed boots.
