This is a kids costume for Wonder Woman, who is known as Princess Diana of Themyscira and also has a secret civilian identity as Diana Prince. She's a DC super-heroine from the Amazonian Jungle, and she's incredibly strong and fast. She also has some pretty cool weapons, like a lasso of truth, a tiara, and bullet-proof bracelets. She teams up with friends like Batman and Superman in the Justice League to fight crime wherever it may be hiding.
