This Nightmare Before Christmas Jack Skellington costume is not only impressive to look at but very fun to wear as well. It’s one of the most recognizable costumes out there! At the neckline, it’s not just a black bow, but a black bat with widespread wings. The jacket should have black and white pinstripes and your pants should be solid black. Any black dress pants will do in this Jack Skellington costume. Wear a nice white dress shirt and some black shoes and you’re nearly done. If you want, you can cover your bare hands by wearing some white gloves.
