I've come across this bodysuit and harness item in ads on Amazon, Alibaba, ebay all the time and I thought it looked really cool. I scanned the web for every picture I could find. I found a lot of images of the bodysuit by itself and the bodysuit and harness together, but few images of just the harness. The most common color scheme is purple bodysuit and blue harness, but you can probably generate every color combination.
