The plus side, I read that might be a protype costume and not the final one so maybe they will fix some things. I saw someone photoshop it a little darker and made her boots red and it looked good.
But, she doesn't have the face for Diana. Maybe it's a bad pose, but that's not a "face that could launch a thousand ships."
But with some modfications, I think the costume could work.
Lynda Carter looks like an adult to me; she doesn't. But somewhat I wonder if the fact that I am on the other side of Wonder Woman's age, no one will look right, because my mind will see any actress as "too young".
