The comics describe Wonder Woman as:
Beautiful as Aphrodite, wise as Athena, swifter than Hermes, and stronger than HerculesHow do you draw that?
If you're many artists, you chuck the icon and start drawing a swimsuit model in a "sexy" pose.
As an example, DC took some ribbing thanks to the "variant" cover for JLA #2, which featured the usually tough-looking male members of the JLA, and then a kind of youngish, kittenish version of Wonder Woman. I don't know that there was a better way to make the point that WW needs to be portrayed as a peer to her JLA colleagues and not as the resident cheesecake, but in response fans created the "what if male superheroes posed like Wonder Woman" meme. You sort of hope DC brass hears about these things and applies changes as they go along.
I wasn't a Wonder Woman reader until way late in the game. I was vaguely embarrassed then (and now) to pick up "sexy" covers on comics, and during the 90's, when I was curious about the character, DC was in the middle of experimenting with both good girl and bad girl art on the title. But when Phil Jimenez came on Wonder Woman, I couldn't help but notice the covers weren't cheesecake, the stories were different from everything else I was reading, and when I flipped through the comics, the art was absolutely stunning. I became a fan of the character thanks to the work of Jimenez, and then had a lot of work to do catching up.
