to do it for conforming you must export the obj (weld where you have to I forgot if you can on export from poser, maybe need a modeling proggy) then import that obj (it has no rigging now so its "dynamic") use the cloth room to reshape the item once your happy with that then export the reshaped obj (make sure you export the right frame)  then import the new reshaped obj go to the setup room for it and add the bones back in from the original, adjust joint zones as required

ps file your finger nails then it dont hurt as you pull lumps of hair out ;-)  have fun
