So, here's my interpretation:
The song is about the feeling of slowly losing your mind while being an introvert. All the midsections across the song show this seemingly bored man, bearly reacting to social situations as the song talk about the feeling of coming undone. The sweater in this song represents sanity, and the feeling of slowly being unraveled as the storyteller walks away from it all and going more and more insane. But that's just my two cents on it.
