The four Vampire brothers are citizens of Halloween Town. They are all a different height and width. Two of them are tall and skinny, the other two are fat. They also are apparently of different ranks- Prince, Baron, Lord, and Count. They wear a black cape with red collar and they use black umbrellas to block out the sun during the daytime in some sequences. Taken from The Nightmare Before Xmas Wiki.
