Forget the impostors: this is the real Supergirl.
Superman was rocketed to Earth as a baby to escape the destruction of his home planet, Krypton. In order to watch out for baby Kal-El, his cousin Kara was sent after him. Her ship was knocked off course, however, and took much longer to reach Earth, so instead of the infant she was expecting, she found that her baby cousin was a full-grown man.
Before the second series of Mattel's DC Superheroes line shipped, reports surfaced that a Supergirl variant was on the schedule for a mid-summer release. Fan speculation ran rampant, but seeing how easy this repaint was, it's hard to believe Mattel will do anything harder.
