This pattern has not only been used as a Batman Halloween Costume but the cap was revised to be a sheep costume of with long curved horns made from wooly like sheep material. It was a hit although he was embarrassed. The pattern has been used for many other costumes. It is a size4 and 6, I hope you enjoy making or using parts of this pattern for your little ones. Mine turns 50 soon and he remembers how cool he looked. Thanks
