If you think you’re just seeing things, and think that everyone (including guys) are wearing neck scarves, well you’re not seeing things. They’re a trend on steroids right now. The scarf can be print or solid, and it’s usually made out of a longer, more dense piece of cotton.
Naturally, Target has them by the dozen, and they’re all fantabulous.
PS. Scarves = the easiest accessory for wc-users.
