We made the costume by buying one large wardrobe boy from a moving supply store, cutting it in half, cutting the front panels to shape and painting it. The finishing touches were the Mattel logos, which we printed off, and some handles on the inside, which we made from strips of cloth.
The whole process was time consuming but worth it. The hardest part was trying to fit the two boxes into my Honda Accord. That took some serious effort, but we got them in there.
Total time spent: 5-7 hours
