We also do a test to make sure that there are no reactions to the Bodypaint or liquid latex. Most of the time I look for Shape and personality. The paint covers allot so even though the model is nude it's often that you can't see any tattoos or stretch marks. As for the Shape. I have found that there are all kinds of beautiful women out there and they often are hiding behind there clothing.
Any woman is Beautiful in the right pose.
We just have to find it. I like the normal girl. The girl that could be sitting next to you on the buss. Those are the models that I'm looking for in my art. Personality is the most important thing.
