a plain black tee with a handmade Wonder Woman logo that was just traced and cut out of adhesive felt. made the tutu using blue tulle and added some styrofoam white stars. wore red shin sleeves to look a little like her boots. also made a superhero cape from a bargain tee by cutting it up. Finally paired it with cuffs and a crown made from gold styrofoam and some elastic.
