Hi there!

While you can certainly do this the way you did, you tend to lose the rigging that way (scrunches up, etc.).  BTW, if you use Edit-->Memorize-->Figure immediately after conforming, that may help that a bit.  Conform the garment, zero the garment, Memorize, then save the CR2.

I would have taken a different approach when using it on a morph of the originally intended figure, following the following steps in PP14:

Conform the garment

Copy Morphs from to get the morphs from the figure into the garment

Ensure the following items and checked on the Properties tab:

Include Morphs

Include Scale

You may also want to experiment with Match End Points and Follow Origins to get a better fit as well.

Doing it this way, you retain the original rigging and morphs, plus the movement bones.
