4. the rumor wasn't correct

The well-loved superheroine will play a major role in "Superman V Batman: Dawn of Justice" and fans are eager to know more about Gal Gadot's character. Debunking the previous rumours about Wonder Woman's costume, Joblo reports that a "trusted and proven source" describes the costume using the term "badass." Her costume is going to be "traditional, yet sleeker" but something very practical and "battle ready."

She will wear a blue leather skirt, elbow-length silver-armoured cuffs, a golden tiara and a variant of her traditional red top. As for her weapons, it will include her popular lasso of truth. Along with that she will carry a spear, sword and shield. The shield will be on her back just the way Captain America carries when not using it.
