How do i fix the sagging shoulders here?

i have the rig in T pose but after uploading the shoulders are sagging a lot when just standing in a neutral pose. the second picture is me pushing my shoulders up to what i think it should look like when standing in neutral pose. Any help would be appreciated.

Avatar’s armature does not fit your body. You need to fix it for yourself.
Here is a good tutorial:


i did all the recommended things to fix it, the armature should be correct in every way so i dont know why this happens. any other ideas to fix it?

as much as how correct the bones look from rigging, ultimately it up to the model’s configuration matching towards vrchat’s default animations, try making your shoulder bone smaller
