Superman can't be everywhere at the same time, so Supergirl's got to pick up some of the missions to protect the Earth from evil villains like Darkside. The Girl's Supergirl Tutu Costume features a sleeveless blue dress with a shimmery top that has a large red S symbol emblazoned on the chest and a red tutu skirt with a sheer tulle overlay. The costume also features a super gold belt, red gauntlets, and a red half-cape. If your girl has an upcoming Justice League party to attend, she'll surely want to be ready to attend all the important meetings and villain-kicking action that will take place. With her powers of super strength and flight, she'll be an important member of the team and become excellent friends with other female members of the Justice League, like Wonder Woman, Zatanna, and Hawkgirl.
