The team Coby Persin makes this prank up by choosing the model model to perform the body paint. The model is with the best body structure you could have seen out there. With the paint team, they painted the lower part of the model with tight blue jean. As far as I notice, there is even no panties putting on. With the paint to the lower part, they take her out to the street.
Walking around the cities with the camera behind her, it looks like no one has even noticed that she has nothing on. With the camera team, they even go to the subway train, taking the train with the crowd. No one is 100% sure that if she is something on to her lower part.
The paint is so realistic that you will only see she is wearing a jean. But for us who know what's going on, we tend to see it differently, guys would know what I am talking about, wouldn't you??
