Old Bat Sketch

Back in the day Batman wasn't the fashionista he is now. So when he had to change threads it meant that he knew he was way over his head and had to even the odds against the (usually alien) threat.
When Frank Miller designed his utilitarian armor to fight Superman -Ooops. Spoiler!- on 'The Dark Knight Returns' I was amazed at how effectively he conveyed the notion of a powerful suit of armor with minimal design. There was not even time to throw a Bat symbol on the chest.

I analyzed that design by sketching the suit myself in this old loose doodle I made years ago. Unlike all the Rainbow variations toy companies put out every month, The TDKR armor is a true modern classic.
