I've made a new outfit, and for some reason way too much of the torso is visible in first-person view, causing the body to clip the camera.
How can I change what parts of the outfit are viewable in first-person?

Does no one know how this works? I've tried renaming the parts, I've tried checking the body part assignments and bone weighting, I've tried separating the arms from the rest of the mesh. I can't find anything that should logically be causing the collar to show in first-person along with the arms.
