Diana wearing pants is a 50/50 split for me. I'm too much of a fan of the rebirth battle skirt design to want it but, I'm not 100% opposed to it either. I think the only time Diana has looked good in pants is in Injustice 2.

This look would be fire if they kept the gold primary on her metals, kept the golden eagle on her breast plate, and added the rebirth boots.

Unfortunately, Injustice exists and that WW leaves a bad taste in my mouth as a character and her interactions/character arch in the story. So... that costume is out of the question.
