I cosplay as Bane and the answer to your question is going to depend on how much you want to do on your own vs how much you want to spend. I can't speak to the quality but you can buy the full costume from Amazon and other costume websites.

Here is what I did:

• Mask- I am guessing you want to buy the mask. I picked up mine from Amazon
  
  
• shirt- just a black shirt will do.
  
  
• pants- pick up a pair of black or dark grey cargo pants.
  
  
• vest- I picked up a tab molle vest from Amazon and then made my armor plates by fiberglassing over carved styrofoam, and then painting them and attached to vest with Velcro. I made my own harness and picked up the unique brass buckle from someone on eBay.
  
  
• boots- just a pair of booths that match close enough will be fine.
  
  
• coat- when I priced I found that a real Swedish bomber jacket was just a bit more than a costume one so I got a real one from Amazon.
  
  
• gauntlet- I made mine from scratch from leather.

I have recently got military like Winter coat from Amazon http://www.amazon.com/Bane-Coat-Leather-Jacket-Swedish/dp/B00CJM09X0
I would love to wear it in my future years too!
