When our youngest was little, he loved Blue's Clues. He would watch it over and over. We thought it was only appropriate for him to dress as Steve for Halloween that year. I found some tan pants from a thrift store, but couldn't find a green striped t-shirt. So I made one from polar fleece (which kept him warm on a chilly October night!) His Blue's Clues back pack finished it off. His niece (yes, he was an uncle before he was born!) dressed as Tinkerbell with a costume made by her mom...check out those natural curls!
His older sister went as Cinderella that year. A prom dress worn by another sister was perfect. Just add gloves, choker, and hair band.
