Some clothes do work but the majority seem not to function under the 'body' selection
It seems like most of the FB morphes like heavy, thin, etc only work from the hip and other body parts 

I have noticed that if I  create a morph with  a third party program  such a MorCloth then they work fine..But  if I use the ones that come with the clothing most of the ones in the 'body'
It se

I follow the procedure that  'Dark edge' suggested which is what I usually do anyway-- to no avail. It seems like they are not 'hooked up'......
