years ago the ex-hubby and I bought sumo wrestler costumes that inflated. They weren't like the ones you see on tv...they were made out of some sort of parachute type material and had a built in fan that kept them inflated. They had velcro around the legs, arms and neck to keep the air in and were the hottest things I had ever worn. While we did win the costume contest I never wore it again....and I can hardly look at the pictures, we looked like complete fools!!!
