Like the TDk suit, way too "busy"
Ideally I'd like to see a noir story set in the '40s (Never going to happen though, unfortunately) and have the suit based on the design of the second Dark Knight Returns costume (Classic grey/black, huge pure black logo) but have the materials similar to the ones in Captain America. Clearly protected and not just spandex, but still allows for mobility and doesn't look too intricate.
