Anyone ever done anything outrageous for a Halloween costume? The best I've ever done was make my own, of a Pac-Man Ghost. It was pretty awesome, but I don't even have any pictures.
Basically, I took some shiny blue fabric from a fabric store, about five times the length of my body, maybe a little more, and an old umbrella. I did everything by way of tape, since I'm a man, BTW. I cut the fabric in half and draped it over the umbrella, evenly, so that it made a cross when flattened on the ground. I taped the edges together, did a little cutting at the bottom, and then inverted it, so it would have a smoother connection area thing where the fabric ends met. On this side, using tape again, I made a W mouth and two L shaped eyes. Then, for effect, I cut the the bottom with a /\/\/\/\/\/ shape and cut out some eye holes in the side, since the ghosts always walk sideways to where they are looking.
It wasn't too shabby and only took a few hours. I'd guess this was about three years ago, to boot.
