We had friends, when we lived in the Washinton, DC area, who always had great Halloween costume parties. First, I have to tell you that they had
to have a sense of humor. Their last name is Horney. Believe it or not the wife's name is Gay. And to make things worse, her middle initial is R(uth). You fill in the blanks.
At any rate, for one of their parties, the husband, Brian, dressed as an over-the-hill Superman. Big belly, torn tights, raggedy cape. He was a sight.
Then, one year, our youngest son asked me to make his costume. I asked him what he wanted to be. He replied, "A shower." As in tub and shower. He was in high school at the time and had quite an imagination.
I took a small hula hoop and clipped on shower rings and a cheap, dollar store, shower curtain. Taped some fabric straps to the hula hoop so it could rest on his shoulders. I bent a wire coat hanger in the shape of a crook, with the crook at the top and fastened the bottom of the hanger to the hula hoop in a position over his head. To the crook I taped a plastic funnel upside down and somehow affixed a set of bicycle handlebar streamers, in clear with silver sparkles, inside the funnel to represent the water.
In the end, he really did look like a shower and he was happy.
