This is an on-going topic for a lot of people.
You can model the new clothes in Carrara or any 3D modelling app of choice. to get them to conform I believe you need to rig them with the bones of the Daz character you want them to conform too.
I haven't done any clothes modelling myself... well nothing substantial anyway but I'll look around and see if I can't find some solid answers to this one.
Seems like everyone makes skirts or t-shirts but it would be nice to see a few tut's on more complicated clothing.
I'll dig around, if i find something good I'll post it here... else I guess I'll have to make a tutorial!
