I have read all the posts, but I'm a bit confused about conforming clothes and perfect fitting ways

Case 1 -

• I V4 unaltered, then the body without any kind of morph
• I have a conforming dress designed for V4
  I conform the dress to V4 and if need be I make some small adjustments.

Case 2 -

• I have V4 with some V4 morph (bigger breasts - larger hips)
• I have a conforming dress designed to V4

If the dress does not have the parameters i changed to V4, usually use "Morphing Clothes" to add them to dress and with a bit of work I can fix it, not always the result is optimal.

Reading the posts above seemed to understand (English is not my mother language) that there is a more efficient way to do what i described in case 2, especially to get a perfect fitting conforming dress.

I understand right ?
If so what is the best method among those listed above in your posts for a perfect fit between a conforming dress designed for V4 and V4 itself ?

thanks in advance
