Review on Adjustable Leather Harness: a Stylish Clubwear Costume and Accessory for Men's Belts by Luis Thompson

This would be a good prototype. It is very faux leather, black and slightly shiny. Difficult to put on (a good pair of corrective lenses would be nice). Even when you put it on, it won't stay on. It can stay on for two minutes at a costume party. Forget any other use, such as foreplay. This is a good pattern if you want to make a real leather harness.
