The Flash Costumes - Adult, Kid Flash Halloween Costumes. While this might not exactly be what the original Flash costume looks like, which was really more of a t-shirt with a funny metal hat that looks like something that Thor would wear, this adult Flash costume draws inspiration from the Barry Allen days of The Flash. It captures the bright reds and simple designs on the suit most commonly associated with the hero.
