If the clothes are for personal use only you can cheat a whole bunch. D3D has a program where you load a character and set an offset, etc, and make a new mesh from the base mesh. I started this way, as the rigging seemed to be the issues you see posted the most about. I took the expanded mesh which had the right groups and made some simple shirts and pants and learned to rig, and learn about fall off zones and then conform first, then create my own clothes models later. Sort of working backwards so to speak.
