I know someone - the guy at Sherlock Studios, I think, don't remember the URL - had a few Victorian characters. They came out around the time P4 was released, so I don't remember if they were P3 or P3 characters, and they didn't have conforming clothes - the coats were part of the meshes, I think. You might want to hunt for that. Or check PoserWorld; they've got some period stuff available and some planned for release on the next CD.
