This is not your average Halloween costume. This is the Inflatable Alien Costume for Adults, and it’s guaranteed to blow all other costumes out of the water (or out of this world). It starts with an inflatable suit that secures at the back with a zipper down the center. Then, when you turn on the battery operated fan, you’ll be fully inflated in seconds. The battery pack fits conveniently into a pocket on the right side seam of the suit, so you can easily reach it and switch it off when you’re ready to deflate. Top of head has alien eyes printed on and hand have long green fingers for maximum effect. Requires 4x AA batteries (not included).
