"I have not seen a single conforming item for either male that does not have oversized balloon shoulders. It makes business jackets particularly ridiculous looking. I simply cannot stand to use any conforming items on these figures except for sleeveless shirts or armor."

You can easily fix shoulders by either using ColorCurvatour's MorphLoader script and a modeller of your choice, or Poser's built in MorphBrush.
