Well in my experience apparently men are more visual or sexual creatures, as in, they are attracted to, or pleased by, a very attractive woman or a woman showing some skin. It's just the way they're built. No-one can mess with biology. Women on the other hand, are attracted or pleased by how a man is, decent, funny, etc as well as money. It's interesting that many male led films are about how a man can get money or mans struggle for it and there's almost always a funny male sidekick. But with female lead films it's normally about how to be beautiful and romantically available for a man. So it's interesting that Hollywood as a whole in general basically teaches people how to be attractive to the opposite sex.
I love it whenever there's a film or an idea which basically opposes that. Wonder Woman is a very domineering woman, she is very in charge and physically strong. She is an icon for female physical strength and female fitness. Just like men who pose on Men's fitness magazines topless, she shows her fitness in her outfit. She isn't about how to be romantically available, but how to be physically strong and in control of your environment.
But she is not attractive in the traditional sense, in terms of a romantically available. Men don't want to be domineered. But she still has to be appealing.
I think this outfit is perfectly fine for WW. No more, no less.
