Do you know the show Fairly Odd parents on nick? well you could be cosmo and wanda. cosmo wears black pants, white long sleeve button up shirt with a back tie, his hair is green and wanda wears a yellow t shirt and black pants and her hair is pink. you can make wings, wand,& crown from carbord and cover the wings in tin foil or you can go to the dollar tree and buy the kids fairy wings glue yellow construction paper over the crown and star of the wand the crown floats above their head so you can get head band and wrap a pipe cleaner around it and then tape the crown to it so it looks like it is floating above your headand they don't wear shoes so i would wear black socks but if you need too wear shoes i would try to go with black. if you need picture referance go to
