Batwoman Costume

Batwoman is one of the comics classics, but where to find Batwoman costume? I looked around online and I noticed it's pretty hard to get the original costume from the comic books.

There are few Batwoman costumes on Amazon and eBay. It's Batman Rises Halloween costume for adults. It's black costume, made of polyester, with short corset dress with black cape, headband with bat ears and eye mask.
