A few years back, I bought some light blue sheets, wrapped them around myself, pinned on a sun and some clouds cut out of felt, and when people asked what I was, said “partly sunny with a chance of rain” and spritzed them.
It was a big hit. And very quick, easy and inexpensive to put together.
You can have that idea for free—I got it from a friend, and of course I can’t use it again in this town. I passed the costume itself to a friend in a different town.
Okay, now give me one.
