If its a full WM rig like Antonia weightmap then the setup room does a great job of transfering the rigging so long as the outfit fits the zero pose of the character

This one seems to be a bit of a hybrid so I'm not sure how well the setup room will do

Quote - I saw this in Nerd3D's readme:

Conforming clothing will still conform, but it won't work very well as it will still be using legacy rigging. Poser has a feature Figure >  Copy Joint Zones From … allows you to copy the weight maps from the target to the conforming clothing. It won't fit perfectly but it will be closer. There are other factors to make the clothes conform perfectly. Dynamic clothing made for Victoria 4 will work perfectly.
