Actually, Wolfie, I posted this before the lesson... "Yes, you can import an object into Poser and take it into the Cloth Room. You can take a conforming Cloth item into the Cloth room, but if you do make sure it is one complete piece that you are making dynamic. For example, you can make the skirt part of a dress (a good example would be the MFD). Say you want to show V4 sitting in a skirt and you can't get a good enough working of the conforming skirt to look right. Go into the cloth Room, Clotherize the skirt  and have V4 sit down on a chair or even cross her legs. The skirt will follow."

When you're setting up the simulation, Poser will ask you if you wish to clothify an object. In this case you just pick the Hip since that is what you want to clothify. The body part could be named something else like 'skirt" or "dress" so that is what you will select to clothify.*
