This is definitely a suit deliberately designed to be grotesque, to not flow together, to deliberately look more like disparate and separate components almost literally strapped together as armor, with total function over form as a design philosophy save for the mask and the symbol.
They didn’t want this thing to work together the way a usual costume design would.
That’s the biggest design break from Nolan; all the Nolan costumes, for heroes and villains, were meant to work together and maintain some degree of grace in the aesthetic. They definitely don’t want that at all.
It’s a bit like they wanted the entire suit to mimic the design of the belt; seemingly uneven and ugly, but all seeming to have some purpose.
I don’t mind it... but I fully expect the film to show this thing getting beat to hell and messed up quite a bit.
