I found a better belt on BCheap.com that has a metal four skull brass knockle design with a plain black belt. So, I ordered the new belt for $15.
The problem with great belts for a costume like this is the price. There are goth stores on line that sell spike belts with metal skull belt buckles. But, they cost $70 even on Ebay. I would never spend $70 on a belt for myself, much less a costume accessory. It's no simple task finding affordable costumes stuff for a cool look.
