When asked whether Wonder Woman fighting crime in a skimpy outfit is believable, Batman vs. Superman costume designer Michael Wilkinson told an interviewer that Roman gladiators did it all the time, and when prompted by the interviewer, continued that those sorts of costumes worked cinematically in Thor and 300.
This seemingly jives with reports circulating online that Wonder Woman will be more Xena than Sports Illustrated swimsuit model in the new film.
Wilkinson, who also said that he designed the new Batman costume and that he's "tweaking" the Man of Steel suit for the new film, said of reimagining Wonder Woman for a new generation, "It's a thrilling and slightly scary prospect of course. It's so important to get her right. She really deserves to be presented on-screen in her full glory, so what I do is look at the history of the character has been presented on the big-screen, small-screen, comic books, and graphic novels; we process it all. Then we kind of put that aside and work out what it right for our film, for the cinematic universe that our director Zack Snyder is putting together. We try to create a Wonder Woman relevant for today's audiences."
That's when the interviewer prodded him about the skimpy outfit; Wilkinson first said "absolutely," then added, "You just have to look at the gladiators from ancient Rome, they did their thing in little loincloths and a shield....Yes, it works for Thor, it works for 300, so let's see what happens."
