Kind of a tl;dr post so I'll bold the actual questions if you'd rather not much through context.

My little brother is spending his summer working on his upcoming practicum for his graphic art degree. Trying to be a helpful sister I'm going to lend a hand doing grunt work for him. His project involves some clothing elements he can't buy online and, since I'm a modeler, I'm going to try and do them for him. He likes dynamic clothing (and with those fancy college workterminals, who wouldn't?). The issue is: I've never made one. When I do use poser-esque software (I'm more of a Zbursh artist) I use DAZ Studio 3. I'm all too happy to get software to help my kin but I had to wonder about the following questions:

Can a piece of poser (probably 8) clothing have more then one 'fabric'? Like, can there be stiffer leather sections and looser cloth sections, probably along shading regions?.

Are cloth settings saved with the item when packaging? I'll be sending things to him at his college so packaging it as close to 'fresh from the rendo store' as possible will make his life easy.

Every time I see a dynamic clothign item, it's very loose, hangy and plain, no doubt to take full benefit of the cloth simulation; can dynamic clothing items have uv maps or does the simulation mess up UV maps too much**?**

Lastly: are there any no-nos for making the meshes for dynamic clothing to prevent massive errors?

I have experience making conforming clothing, but this is a bit outside of my familiarity. I'm happy to learn the ins and outs of designing, but these questions probably should be addressed before I start making meshes in a bad way. Any tutorials related to making dynamic clothing would be appreciated as well.
