hi, 
so im pretty new to CC4 and I've been battling this for about a week now and honestly i'm about to throw it in the bin..  i created some clothing in zbrush, uv'd remeshed it etc to the way i wanted it i imported it into CC4 as a cloth asset and transferred skin weights set to default option ( ive also tried setting all the bone scales to 0, and 1 ) but i can't seem to get rid of the annoying stretching on the clothing. at the armpits & groin area.

can someone please help me understand how to fix the skin weights 
I've added some screenshots of the stretching areas and the bone weights in the broken areas.
