" If all superheroines were as indestructible as Superman, leaping across rooftops, smashing through windows, and flying through flames in a skimpy swimsuit wouldn't be such a problem. However, male heroes are usually presented as being unquestionably more powerful than women.Yet, they wear costumes that cover and protect most of their bodies. Women on the other hand, are written as weaker, and presumable less able to protect themselves. Yet they charge into battle with most of their bodies exposed...............................................
...............The reason for this superhero fashion double standard is that comic books have always been primarily targeted to a heterosexual male reader. As a result, female superheroes must look attractive to these readers. And in the world of male fantasy, attractive= sexy. So, revealing costumes are fitted onto idealized bodies with large breasts, tiny waists and impossible long legs. Men need to look powerful and virile, but can't display bulging genitalia showing through their spandex, as it would be too threatening for most straight male readers. "
