I'm not sure why this happens.  In the first place the dress is in proper position for the simulation ... then by frame 7 of 30 frames it has an outrages number next to the frame number. (222 or 300 somthing) and fails.  Here is the first frame. Any help would be greatly appreciated.

And here is what it looks like at  the failure in frame 7.  (I've marked collisions and applied collitions to all of the bodyparts to guarantee no poke throughs ... she is crouching in the end of the "animation").

I don't know what to think ... I've had this happen to other simulations too ... to the point I change the clothing to conforming.  I'd rather not do that since dynamic looks so much better when done right.

Again thanks for all the help I can get.

what I do to test the item is set up a simulation , just dropping the item to the floor.

If any parts seperate then the mesh is not properly constructed for cloth sims.

You can export and re-import specifying "weld" and try it again.

with that tight a dress I would look at collision depth as well.

I'll look into that.  I'm also thinking that maybe the fact that the under arms are touching the dress and that is corrupting the simulation.  Thank you.

This is almost certainly the cause of your problems.
Start the simulation with the arms straight out to the side, and set the final pose in frame 10 (or so).

Adding vertices to the constrained group in the underarm area may help if you don't want to adjust the final pose.
You could use Poser's collision detection to determine how to adjust the final pose to make sure the arms don't trap the cloth.

Actually I've corrected the arm problem.  I just made the arms exempt from the simmulation.  But, I found that I had made the final pose (crouching) tore the skirt apart.  I've worked with stretch dials and friction and almost have it right.  But it still crashes about frame 28 of 30.  I'm getting there though.  :)
