I think it would be better to ask, where does a snake wear a tie?

My neck has a clear end, and the purpose of a tie is to (arguably, I’m just guessing here) tie off the collar of your shirt, what kind of shirt would a snake wear? The tie for humans is arguably more related to our body shape than neck components, so you can’t even say relative to a comparable organ or bone. So where does a snake wear a tie?
