There's the Digital Tailor stuff in the Rendo marketplace by Fugazi1968 and ironman13 as a start. Marvelous Designer seems good for the Dynamics. Jen Greenlees has some old (PoserPros?) tutorials for using Hexagon to model clothes up on Youtube.

Any modeling software should be good as long as you are familiar with it. (Blender since 2.79-80, with the interface changes seems very good and its FREE! ) Look for terrymcg on Deviantart as models the stuff he posts.

Hope this helps some.
