ah, I actually think it would be a good take on the character, if he was constantly having to fix the costume. One, it could be a good ongoing joke. And two, unless everybody on Krypton wears red capes and blue spandos, it makes no sense for his peops to send him that uber cool outfit.
the aura was part of his invulnerability. If nothing could get through to his clothes, then that same 'aura' would also keep things from making it to his skin. (comics over 20 years old, should be out on the internet for free, that would make this place much more interesting)
