WardrobeWizard is really great. And very easy to use. Load the cloth and the original figure, zero (included!) and let WW calculate. Then load the morphed (or other) character/figure, zero it and have it calculated. There are even warning messages when you do something wrong.

 

Sometimes, when poses are rather extreme, the cloth mesh will not exactly follow the body anymore as the bodymesh is deformed due to posing. This has nothing to do with WW. In this case, magnets can be used.

 

I have tried prudent planning long enough. From now I'll be mad. (Rumi)
