Are bony collarbones/shoulders unattractive?

No, not really. Actually a girl in my school came up to me and told me that I have a very attractive collar bone. It was a bit awkward but I guess some people find it attractive. It's something overlooked for sure. People normally don't think of it as attractive or unattractive because its right in between the face and the , so people just look past that area. It's not something to obsess over. The only reason someone would even look there would be if you were wearing a necklace or you are pretty flat-chested (like me) and are wearing a v-neck
