Took 7 minutes from download to this result on a morphed Poser4 Lo Res Female figure.

Clothing available here:
http://www.renderosity.com/mod/freestuff/details.php?item_id=72704

Steps to reproduce:
Download the free clothing.
Import the Top and the Bottom Object files.
Scale to fit to this extra Lo Poly figure.
I Used Morph brushes, Tighten and Smooth to Adapt/Fit to the morphed Poser4 Lo Res female.

Rebuild materials. (I imported the object files and not the pp2)

Select Bottom, Smart Prop it to the hip. (select the inherit bends option)
Select Top, Smart Prop it to the abdomen. (select the inherit bends option)

Smart Propped clothing follows all bends from the parented group, one group up, and one group down.
Instant clothing, no rigging required.

Thanks Joanna for this free item.

Just to show the usability of the newer morph brushes.
Happy Posering, Tony
