You may want to try and create yourself a BlankCR2 fir your figure and use that to rig the clothing with, using clothing to rig other clothing can become messy.

Blank CR2:
Remove all of the morphs from the CR2 (MorphManager) then save to the figures library as BalnkCR2. It's basically a developer rig done before there were developer rigs.

Hope this helps.

Comitted to excellence through art.
