Is that your actual face painted or is it a mask for the joker? Or is that even a costume (looks more like a statue) since its dead on the movie style.
For an actual Batman suit, there are a number of people I think can help you on the League of Heroes message board - but that is a severely more complicated - and more expensive costume to put together.
I saw two listings on ebay recently, 2.5k and 2.8k. I think ones from spidey4fun and the other from a dark knight short film they made. They both look superb. If only I had the money lol. However the cheaper one is custom made for your size is what I gather from the listing
Batman "can i ask you something?"
random docter "what is it now?"
Batman "can you ask me that again but with more words?"
random docter "what is you want to.."
Batman "I'M BATMAN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
