That trick only works with matching full-body morphs and P4's crosstalk bug. Poser 5 eliminated crosstalk. I think nerd discovered an autoconform workaround for the crosstalk fix, but I haven't read up on it. When you conform an item, all its morphs are set to their default values. The morphs you transferred have a default value of 0, apparently. To change the defaults, first set the clothing figure's morphs, then Edit menu --> Memorize Figure, and resave the item to the Library.
