Up, up and away this Halloween with the Supergirl TV Show Child Costume Included in the set is a dress, gold belt and removable red cape. The dress has a red skirt, blue bodice and a large S logo on top. Finally, after years out of the spotlight, Supergirl has her own TV show. This officially licensed outfit is designed to look like the one worn by Melissa Benoist in the show. Kara Zor-El arrived on earth much later than expected. She was supposed to care for her cousin Kal-El, but while she was in space in suspended animation, he grew up. As an adult, she becomes a superhero but she starts out in the shadow of her more famous cousin and struggles to reach the bar he has set. We know that kids who have older brothers and sisters can relate to that feeling.
