You don't actually think women are obsessed with clothes, do you?

A few weeks ago, on Feministe, I saw the following comment:

They actually did a run of Wonder Woman in the seventies that involved both changing her powers (they made her more of a karate chick than a superhero… that was lame) and changed her costume to an Emma Peel style jumpsuit. There was OUTRAGE! It was incredibly short lived.

According to wiki, some of the loudest voices calling for WW to be changed back came from feminist groups. Make of that what you will.

The context of the discussion was Wonder Woman's costume, but the truth of the matter is that Gloria Steinem didn't want DC's foremost female superhero to be depowered. (Source: Wizard Magazine #177) The bathing suit wasn't the central issue (Edit: It just got her attention, Thanks Marionette). Now, this irked me, and confused me, but I let it pass as I wasn't entirely certain of the facts until I read an article. It was a silly assumption on the Feministe Poster's part (or else she'd have never brought it up while the conversation was centered on her costume), and I should have seen the difference immediately. The context clues had thrown me and I laughed to myself now that it made sense.

Still, I have to wonder, why is it when there's complaints about the weak portrayal of female characters in superhero comics is it conversation always assumed to be the costumes and not the serious sexism/misogyny in the plot and characterization?
