Via email I suggested the following:-

Select the clothing.
Go to the Poser menu Figure > Copy joints from > Ryan

Check the pose, sometimes the same effective pose can be created by rotating the collar less and the shoulder more.

Also remember that the P4 Men's Turtleneck model is very low resolution. It may not be a bad thing to take it into your 3D modeling application and do some subdivision on it. Be sure to retain the group names. If you have UV Mapper then you can do it easily in that.

I also commented that the second capsule is just there to add extra refinement. In some cases the effect is so small that it is hardly required IMHO :)
