I think it's like wearing a cap for them. Just a head dress, when I was a teen I always had my cap on my head where ever I went, my dad hated it lol. In my head I thought it made me look cool, maybe they are thinking the same thing, I do hope they grow out of it.
I'm wearing a bandana right now. I like having something on my head, it doesn't get overheated like a toque does, it's relatively uncommon around where I am, I'm alright with the way it looks, and why does it matter?
