I agree with RobynsVeil. PhilC's obj2cr2 is an absolute must-Have.  You still need to  do a few simple dress and t-Shirts manually though, to understand the process (which is not difficult).

When pjz99 doesn't agree, we must examine his background.  And if you do, you will discern that pjz99 favor a minimalistic style with very simple mesh, easy to group. It is his style quite simple, nothing wrong with that. However if you try to rig the more complicated models from Marvelous Designer with overlapping cloth and what not, life is too short to forego obj2cr2.

This little incident illustrates how important it is to know a persons background before evaluating his views.
