A morph must be done on each of the clothing groups that fits the body shape. Multipy each of the possible body shapes, by each clothing item of interest, by the number of groups in each and you should see the potential magnitude of the problem. The magnets can get you part the way there. If you can get the zones and limits set, you can use the setup on any item of clothing with the same groups. You need a modeling program to get fine control. Which program is more a matter of preference and comfort than it is any real difference in output.
