The Superman costume has been tweaked and reworked repeatedly and no one is really sure what the final version is going to be. One thing is sure, though: the red underwear over the costume is a thing of the past. Some of the latest leaked versions appear to have some armor look to the entire costume. Pictures have been surfacing of various sketches and designs; likely to keep people guessing until the final design is released officially. There has even been one with a sketch of a short sleeved costume.
The last photo shows different touches like a v- design to the neck and to the wrists, allowing the sleeves to come down slightly over the hands. The cape remains in place, but the other changes can really make your head reel. The Man of Steel may never have looked better!
