I got permission from oldflash to use his Handmaiden model to make Brianna look different than her sisters. Thing is though, I'm not sure how actually do it. I want to make it so that the body models are still the same, but Brianna uses oldflash's head model while the sisters use the orginal head. What do I need to do?

Please don't post duplicate threads. Use the one already open in Holowan--thanks.
