I bought the dress that I turned into the vest on Ebay and customized the heck out of it (I didn't want to sew any zippers in myself so I took the easy way out... I HATE ZIPPERS) and the rest of it I made from pattern or already had laying around my house. The prop is the funny part. I play Bass guitar and my guitar case looks like Harukos. I put plastic Peanuts and a cardboard pipe inside of it to help it hole the shape and keep it light enough to pick up and swing around.
