Vampire Child Halloween Costume Boys Large (8-10) It must be difficult to raise a little vampire, but it's manageable. Besides the overwhelming need to drink blood, they are mostly well behaved. The Boys Vampire Costume features luxurious red vest with an attached white shirt with a satin-like front, a pair of black pants, and a matching black cape. This is a great take on the classic vampire look that was made popular in early media and would perfectly suit a colonial era themed party. It's true that your son would stand out and the folks would probably flee in terror, but what's a party without a little high energy excitement? He will surely be a fan of this outfit and find every excuse he can to at least wear the cape daily.
