This arguement is not directly to you, but I just wanted to throw my opinion on this matter.
People always use this excuse to defend the Nolan Batman costume.
And I completely disagree. Don't take this to mean that I hate the costume or anything, btw. I find it perfectly fine.
BUT, if they really wanted to stick to the comic costume, they could just as easily have. Look at how Batman: Arkham Asylum and Batman: Arkham City did the costume. The costume from those games would have worked just as perfectly in Nolan-verse. Both those universes are tonally very similar too, and so the costume would work.
