Crewel's hair is parted at the side, with the longer section colored white and the shorter section black. He has narrow grey eyes and wears silver studs in his ears. Beneath a thick, black-and-white furry coat, Crewel wears a tuxedo—consisting of a black dress shirt, red tie, a black-and-white vest, black dress pants, black dress shoes, and a black belt with a silver buckle, studs, and spiky sections. He also wears red gloves.
