Your little Supergirl will love embracing their superhuman abilities in our adorable all-in-one costume. It comes with a layered tulle skirt and ruffle details and a cape, of course, as well as a bow headband. The one touch fastenings make this costume easy to pop off and on, but we have a feeling they won't want to take it off! Please note that for dress up styles under 3 years the appearance and features may vary due to safety reasons. Bringing books to life.
