Honestly I am wondering if they are going the same route they did with Mr.Freeze (it took 3 episodes), Scarecrow (3 different cosutmes over the course of 6 episodes) and Jerome/Jerimiah (technically due to the fact with post season 3, they add more elements of the Joker with each appearance) , and the costume we are seeing for Bane right now is just the prototype costume before we see other more finalized versions of those costumes (whether it is more comics, Arkham game or Nolanverse inspired or take a combined mix of all 3).
As it is right now, yeah I think the shoulder pads are my biggest gripe with the costumes, but others elements don't really take me off that bad. It seems like based off of tweets like this () and interviews like the Newsrama one, they are trying to shove as much Batman lore reference into these 10 episodes as they can. Hopefully it doesn't overloads and takes away from the overall story.
