The animation above shows clearly, if nothing else, that the difference between "nude" and "clothed" in comics is coloring. That is all. She seems to be actually "wearing" more "clothes" in the Jim Lee design -- as in, there are more pouches and lines and things. For all we know the flesh-colored portions of her costume are actually peach spandex like figure skaters wear.
It's silly to say that male comic book characters don't show skin because:
a) basically everyone in comics is completely naked all the time. b) the freaking Silver Surfer proves this a million times.
Is there something wrong here?
Yes, there is almost certainly something wrong with the Nevernude family. Yes there is a huge problem with sexism in comics. I personally feel it falls more with dialogue and plot than with the art.
Every character in comics is a hypersexual god, male female or inbetween. In most how-to books they specifically tell you how to draw "heroic" anatomy.
Talking about how much "skin" they show doesn't mean much to me, or DC. If you complain about it too much, they will start coloring the "skin" portions blue or purple or something, and continue to draw them exactly the same way. frex Tina from the Metal Men (a staggeringly sexist creation, but more from the way she spoke and acted than the way she looked, because they were ALL naked shapeshifters).
I think a lot of you are aware of the problem but are misdiagnosing it, and thereby pushing the signal-to-noise ratio down for the people who are actually trying to fix the problem.
