Quote - I've tried using BreastMale at .400 along with BreastSize2 at .272 and BreastGone at .420. They look good until you use any poses with the arms raised higher than her shoulders. With those poses the breasts seem to cave into the chest. However using lower settings(although breasts will be slightly larger) seem to do well.

You probably need to manually adjust the JCMs that are causing this problem.
