PhilC would be the first place to look for clothes-part-of-the-figure models. And you're talking old stuff; that way of doing things pretty well faded out when P4 came in. But it would fit with architectural visualisation, especially since most of the figures are quite distant and posed rather ordinarily--no big bends. And, as with movies, you can probably do a lot of the detail with textures and bump maps. There are other sylized figures out there--DAZ do a couple, best bought in one of the bundles, I think. Cartoon business people, rather than just simple.
