Another question .. I wonder if part of the problem is in understanding what you mean by "conform to" ...

"Conforming" a piece of clothing to a figure simply means that you "attach" the clothing to the figure so that when you pose the figure, the clothing automatically follows it.

Now ... if you are talking about clothing that fits an actor (for example, if you made a dress for V4, but the character has the Voluptuous morph dialed in, and you are wondering how you can get your clothing to fit that body shape automatically), that is a whole new ballgame.  Making the clothing "conforming" is the first step in creating content. There is still more for you to learn, but we are trying to take it one step at a time.

So it might help if you explain a little better what you mean by "conform to." I think perhaps if we better understand what you're trying to do, we might be better able to point you in the right direction.
