DISCLAIMER: WHILE I MAY NOT BE A FEMINIST(WHICH IS DUE TO HOW MODERN FEMINIST HAS CHANGED IT'S DEFINITION), I AM IN NO SHAPE OR FORM A MYSOGYNIST, SEXIST, BIGOT, OR AGAINST WOMEN HAVING EQUAL/FAIR RIGHTS!
[UPDATE1] I understand the true meaning of Feminism, and you can say I am true feminist, but I choose not to associate myself with a group that has been tainted to the point that the true definition no longer applies in the slightest. I'm an advocate for HUMAN equality, end of story.
Women's portrayal in comics have been an issue for quite a while now. There are complaints about the way they dress, their physiques, and there not being that many strong female characters.
On the way they dress, yes 80% of the time it's very revealing, but can you honestly not say it's the same for the men? Yes, in most cases they are far more covered, but it doesn't matter when their suits are so tight, it leaves little to the imagination on how they would look completely nude.
Many will say that the physique of female characters in comics are pornstar-ish, while the men get athletic physiques. I have to dissagree here, because when I look at the bodies of the female characters, they look like runners and/or gymnast which is the perfect athletic look for female characters(allows them to be strong, fast, and flexible). When I look at the men, most of them look like body builders, and when I think of athletic for men, I look for them to have more of a basketball player's physique, like The Flash or Spider-Man. Yes, the body builder physique allows them to be immensely strong, but realistically all that muscle would slow them down, and allow little flexibility.
[UPDATE2] Over exaggeration in comicbook females are also a huge concern. Each artist is different, but one thing each have in common, is to create the "perfect" body. For women, the hour glass figure, tone body(legs mostly), breast being no lower than a c-cup(in most cases), and a round firm bottom. This is why posing of female characters are very sexualized, to bring attention to the hour glass figure, the toned legs, arms, and stomach, the breast, and the bottom. Men also have over exxaggerated bodies as well, such as huge and high set chest, washboard abs, and head size bicep and triceps. In posing for male characters appear less sexual because they want you to see the chest, abs, and arms, so they shy from using the "broke back" technique, but the features that do sexual men are the chest, abs, and arms.
I will admit that there are far more male superheroes than there are female, but let's not forget most of these charcters where created in the mid 1900's, during a time when women were looked at much differently than they are today. While this doesn't mean they can't create new female heroes, you shouldn't expect them to just spit out a bunch of them to fill a gap. You want them to take their time, and make sure they do the new character(s) justice, instead of just producing them to keep the female readers happy.
Even with all this said, it doesn't matter. Why? At the end of the day, what matters is that we look up to these characters because of the moral examples they set. Just because Wonder Woman's costume leaves much exposed, we think no less of her because of it; she's strong, smart, and one of the best combatants in all of comics, so the last thing we're thinking about is what's she's wearing and what body type she has, we just want to strive to be like her.
