This children's Supergirl costume may not actually give the girl wearing it the super strength and super speed traits of Superman's cousin, but it will give her the eerie ability to collect large amounts of Halloween candy while trick-or-treating! Costume includes two tone dress with matching cape, lame belt and matching boot tops. Made of polyester material. See drop down menu above for sizes. Trademark and Copyright of DC Comics.
