I really wanted to like that (pictured) redesign of Wonder Woman's outfit when it came out, but the bolero jacket and the weird choker killed it for me. I liked the red and black. I liked that she had pants. I thought the belt was cool. If the red part was supposed to be armor, though, the cleavage dip makes it kind of silly.
Still and all, though, better than the star-spangled hot pants thing she's had going on forever.
I think it would be kind of cool to see Wonder Woman in just regular modern lady clothes, but have transparent-with-golden-outline magical armor form around her when she's doing her superhero thing. (Sort of like Mass Effect's tech armor, but inspired by ancient Greek design. And magical.) Maybe she's always got the magic bracers on and that's where the magic comes from. Maybe one of the ways to more easily show that Wonder Woman is a strong, confident female archetype is to have her dress like one.
Somebody with the power... push that up the chain and make that happen.
