Now you mentioned that the clothing you are attempting dress V3 in is conforming.  Look at the morph dials under properties to determine the morph capacities of the clothing.  They should match fairly closely to your model's morph dials.  If so, copy the settings from your model and apply them to your clothing morph per morph.  This is the quick and dirty way of doing it within poser without 3rd party software like Morph Manager.  Otherwise, save your morphed Vicky as a new figure and transfer the morph settings using Morph Manager or Tailor. 

I always give custom morph clothing a little extra morphing room to give the appearance of actual clothing.  Also, if poke-throughs are a problem and that particular skin area is well covered just make the body part invisible.  Renders will go faster if Poser perceives that there is nothing there.
