Two things to look for; The program you can afford. The program you can work with. Carrara has the Ray Dream/Kai Kruse background that does make it one of the easier programs to pick up and get modeling with. It plays well with Poser, too; and I don't mean the import capabilities (Transposer) but that Carrara can make nicely-grouped meshes that are simple to texture and rig in Poser. That said, Hexagon is a wonderful little modeller, Wings is free, Silo has some specialized tools that can make the job easier. On the subject of morphs -- no 3d program that I know of is really friendly towards the morph process. You'll always end up worrying about scale changes and changes in vertice order or number that cause the morph to fail. That said, Carrara's toolset is about the most primitive one out there for manipulating a surface as needed to create a morph. About the best tool I've found so far in Carrara is bones; rigging a mesh inside Carrara, posing it, and saving out the poses as .obj files to make morphs from. My last recommendation is that clothing modeling is tough stuff; almost as bad as figure modeling (when you include the rigging issues...!) It would be unwise to spend a heap of money then realize you don't enjoy doing it or have no knack for it. Fortunately, Carrara has a full-function demo.
