Via The Mary Sue:
"When invited to a birthday party whose theme required that the boys dress as superheroes and the girls as princesses, dad Jay C. Batzner came up with an awesome compromise that simultaneously stomped on the face of gender normativity and made his daughter happy. Wonder Woman, both a princess and a superhero, had long been Daria’s favorite hero, so he sewed her this costume. We think this might be one of those steps to raising kickass daughters."
Not only does the girl subvert gender stereotypes by going as a superhero, the dad does by sewing her costume!
Bonus points for her name being Daria.
