Giving a bit of hint to the fans, Gadot posted a cryptic message on her Facebook page on Monday saying: "Busy busy week... Let's have a WONDERful week everyone! xoxo."
What had added fuel to the speculation is the use of word "Wonder" in the post. Fans are hoping that the upcoming week has to do something about Wonder Woman which may or may not be about her costume.
The film's costume designer is Michael Wikinson of "American Hustle" fame. Regarding the costume of Wonder Woman Wikinson told The Wrap at their pre-Oscar bash: "It's a thrilling and slightly scary prospect of course. It's so important to get her right. She really deserves to be presented onscreen 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", he said, adding, "Then we kind of put that aside and work out what is 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."
It could so happen that the Wonder Woman costume takes a hiatus from traditional armor design and is closer to modern sensibilities. However, Wikinson did say that there will nothing wrong if an old-fashioned armor of Wonder Woman is used in the film.
"I mean, you just have to look at the Gladiators from ancient Rome, they did their thing... with the shield and everything. Yes, it works for 'Thor' and '300,' so let's see what happens, " he said in the interview.
