As Comic-Con 2011 approaches this weekend, we’ve been celebrating the best-dressed comic book characters on screen, and here is our first villain! Uma Thurman plays an insane scientist (common theme the last two days…) turned Batman nemesis named Poison Ivy. Batman and Robin completely bombed at the box office and with critics, but at least Uma got to wear some fun costumes! Here is our favorite outfit of the movie – an ivy covered leotard with green stockings, matching emerald cape and sheer sleeves. Hey, if it’s an outfit that can turn Chris O’Donnell and George Clooney’s heads, then it has to be sexy!
