I am in search of a boba helmet that will fit on larger head. I am not an alien or anything but my dome measures about 24 inches around. I have purchased two helmets already that won't go completely over my head. I have most of my costume built, but finding a helmet has been the most difficult task I have ran into in all of my costume building. Any advice to where I might search to find a helmet that fits? The last one I tried was made from the mystery helmet mold. Unfortunately it was too tight to go over my heat.
