After struggling through PoserCloth setup, setting values, and rereading the available tutorials, I think I finally got the hang of it. My concern was the draping of skirts with extreme leg bends and how to overcome unusual bunching and poke throughs. I now think I have a better understanding of how to approach the problem. Below are 2 renders of AerySoul's Zoel outfit converted to props in the Fitting Room and used as PoserCloth. Initially, I couldn't overcome the unusual stretching and poke-throughs until I grasped the concept of the Automated Constrains. The images below are my final successful attempts.

                                                                            

Soon, I will try applying what I learned to other converted clothing, as well as existing dynamic clothing in my Library.
