As a SJW, I actually dislike the costume. In my opinion it shows a misunderstanding of what Wonder Woman represents to feminists and what feminism is, and it borders of slut shaming.
You see, contrary to popular belief, Feminists have no problem with sex and nudity; it's the way you portray them. Wonder Woman's bathing suit is fine if she's drawn in strong poses rather than sexualized ones. This one, I dunno it's busy and weird.
As a comic book fan, I prefer the classic costume
