I feel like I'm being shamed for my use of quads in cloth simulation... :-) To justify myself: I'm currently working on a pair of conforming thigh-high stockings, and those did not work well in the cloth room with MDs normal triangle mesh. So, I had MD produce a regular quad mesh and then cleaned up the seams in Blender. But otherwise, I completely agree with FVerbaas. Most meshes out of MD work very nicely in Poser's cloth room with the default triangulation.

T-shaped junctions, piping, hems and multiple cloth layers would probably deserve a thread of its own. I find all of those can help a lot to make a piece of clothing look more "realistic", but they're often tricky to get to work nicely in Poser.
