Korean pop sensation Psy's Gangnam Style took the world by storm. The video featured a hilarious dance and an enthralling presentation, and the song really was pretty catchy. With the Korean Pop Star Boy's Costume, you can help your son look just like Psy this Halloween. This costume features a powder blue blazer, a black bow tie, and a pair of black sunglasses. The blazer is blue with black trim and black buttons, and looks just like the one Psy wears in the Gangnam Style video. All your little guy will need is a white button down shirt, black pants, and black shoes, and he'll look just like the Korean sensation. He'd better learn all the words and all of the dance moves, because everybody is going to want to hear and see them when they see his costume.
