For some users with the new version of GTA, they have a kind of Bugged Jiggle on the breast of the NPC Karen Daniels, this is a fix that gives the normal body for Karen Daniels/Michelle also less neck separation but its impossible to remove the neck separation completely its a really complex character but did my best. :) its almost not noticeable.

INSTALLATION:
Dont forget to backup ur files first!!
