Then what do I need to learn so the clothing I made fit the actor for the person who wants to use it without them having to conform the clothing? Or is that important?

Well, let me ask you this ... I'm trying to determine if I am understanding you correctly.

I'm assuming that you have used other figures and purchased or downloaded clothing yourself?  If you buy clothing for V4, for example, it is made to fit V4. But you still have to conform it to the V4 in your scene, correct?

Are you asking if there is something that you can do to make it work differently, so that you don't HAVE to conform it to the figure?  Or is there something else relating to something that you have purchased, and you're trying to figure out how to make it work?
