Multiple options here:

1. Make the underlying part invisible.
   2, Use the morph brush in later Poser vesions
   3; Take the clothing to a 3D app and correct.

2. If the poking is only light, you can put a displacement map on the clothing.

3. Set crease angle of the figure to a very low level, like 50-60 and set the crease angle of the clothing to a HIGH level like 180. Render with Smoothing ON.
   Smoothed objects expand. The clothing will expand over the figure.

Remember;

Subdevided figures decrease in size They SHRINK.

Smoothed figures/objects expand and GROW in size.

Happy Posering
