I had a friend make a Jill Valentine (Resident Evil) costume recently, and that suit is also leather-like with a honeycomb pattern on it, though not as intricate looking as the one you're thinking of. She made a stencil and then used paint to stencil the honeycomb onto the suit. It took a really long time, but it looked very nice and very accurate after it was done.
Here's a ref photo of Jill: http://toydirt.com/wp-content/upload...-Version-5.jpg
