I agree with Afrodite-Ohki that a good hand-shaped morph would most probably give a better quality. Also, there is still no copyright problem in doing an Antonia morph for V4, since Antonia uses an open licence. What is the problem here? If you don't want to use V4, you can easily transform Antonia to V4 with the Refitter as well, and start converting clothes without a V4 in the scene.

Seriously, are there any drawbacks in using the mesh which most clothes were made for?
