Throughout the years Wonder Woman has had many different costumes but she has been sporting the Warrior look since the 1980s, Thats right folks; the 80s which was long before the Xena television series was created. If you need proof, feel free to Google Warrior Wonder Woman by George Perez which was done in the 80s and you will see for yourself. Princess Diana has been kicking butt in it ever since. If anything, Xena was inspired by Wonder Woman not the other way around. Perhaps you should stop calling yourselves fan boys when it seems like your only goal is to rip apart uncompleted films. You have demonstrated an obvious lack of knowledge on the history of the character in comics.
For those of you who say the movie costume is a rip off of Xena; your argument is invalid.
