Fixing bad weight paint on body mesh

[bernt92]

Hi! I have run into a pretty annoying issue with a body mesh that I have. The body weights seem to work fine for the most of the body parts, except for the clavicle part og the body. Whenever the character stretches it's arms the sides of its back moves with it, causing a pretty ugly stretching effect. I think the clavicle part is the issue, but I'm not exactly sure about that yet. 

I have tried to figure this issue out in outfit studio, but I can't seem to find out what's causing that part to move with the arms. 

The body shape is a MTF kind of thing/male to female), and it has been modified earlier by someone else and this issue came with the bodyfiles I downloaded. It is also based on a COSIO female body(clams of skyrim). 

Does anyone here have the time to maybe have a look at the mesh and maybe figure out what's causing the bad stretching? I have tried literally everything, but I can't find out what's wrong and I can't fix it. 

 

Hope anyone can help me with this!

I'll also mention that it seems in game that the part I referred to is connected to an armor piece for the arms  that is not there anymore, and therefore moves with the arms. But I can't figure out how to deal with this. I've tried to copy bone weights, or selected weights for that part, both from a male body and from a female body, but everytime I get no weights at all on the Clavicle area and it looks even more ugly in game.
