One thing that has resulted from COVID is that people purchased lots of bandannas, and I did too. Recently I realized I could just wear one around my neck even inside my home to stay warmer, which is something I'd somehow never considered before. It's more comfortable than a turtle neck imo.

I think a lot of people had this same idea, and you see bandannas being worn around a lot. In public people will just think it's your 'backup COVID mask' if you have a bandanna around your neck, so it doesn't look like an oddball style choice.
