The mannikin contains morphs that are the V3 shape, so this together will The Tailor convert V1 clothing to V3 - as far as the shape is concerned. There are pose file to change the JP to V3 JP going in. P-Wizard, or hacking, will get you a CR2 that matches V3 for real. What these cannot do, is match the seams of the groups to correspond to V3 - and V1 is cut somewhat differently from V3. A problem I discovered in recutting the group shapes - it alters the mapping - espcially the old style Zygote mapping where the front and back of the model are spread all over the map. None of this has any affect on a skirt. Skirts do not conform worth a damn. Not with leg movements, they don't. Steve Shanks has had some success, but morphs to replace the poorly functioning JP are the best solution now. The problem with this and P5 is that the morphs cannot be JCM. The cross-talk fix erased this function in conforming clothing. All any clothing can do - is fit a figure at zero pose. It is up to conforming and the JPs' dynamic magnets to adapt the clothing mesh to joint movements - and that is strictly Poser.
