I just started making cloth a couple of months ago still I have made some observations.

The cloth made by the very best for instance the guys who work as employees for Daz is very good, pockethru is kept to a minimum and the mesh is almost uncanny perfect. Still, if you compare their work to the real world they are somewhat lacking in the design and fashion department. My guess is that if you are making more cool looking cloth and texture, that will outweight any minor deficits. After all that's what apparel exist for isn't it?

I started to use the AutoGroup Editor and then changed to obj2cr2 as it is more accurate. But after a while I returned to AutoGroup Editor. Why? Because with obj2cr2 you have only one shot, either it works or it do not. The AutoGroup Editor is more forgiving in that you can do a manual correction of the result in your modeler program, and experiment with different donors.

The main differens with commercial clothes vs for own use is tons of morphs and magnets, and hours of corrections of pocketthru. Very boring.
