Also, I sometimes find it useful to adjust the centre of a part in the clothing (upper arm, lower arm, thigh etc), through the Joint Parameter menu.  There is a tutorial at PhilC's website that very shows how to do this - quite simple.  It does get the clothes to fit and move with the figure better.
