Part of the problem with "think like Wonder Woman" is that there's rarely a consistency between artists. So I guess to go the Wondy route, it would make sense to ask which artist you think represents her "proper" shape best. I'm rather fond of Nicola Scott's take on her, myself.

And yes, practical costumes are love. Practicality vs. public expectation was pretty much the whole reason why I figured there'd be two costumes for a female Cap, rather than the one male Cap uses all the time (though I imagine once unfrozen, the practical one would be used a lot more, both because the show one would probably be a museum piece, and because social mores have changed).
