What am I?

Let's play a game.

One person will post and give a brief description of something. Other people have to guess what it is (one guess per post). Simple! The first person to guess correctly (after being confirmed as the right answer by the one who asked the question) will then ask their own question. If the person who answered the question correctly doesn't ask their own question within *ring ring* "7 days" then anybody else is free to jump in and start things rolling again. Let's see how it goes!

So to start things off simply:

"I'm something you wear on your head, what am I?"

It can't be as simple as a hat. Can it?

It can't be as simple as a hat. Can it?

Correct! Your go.
