Last week on January 15th was International Hat day. People all around the world wear fun hats in a very spirited fashion.

The origin of this odd festivity is uncertain. However, it comes every year and is the best occasion to show that unique hat you've kept secret in your wardrobe.

Everyone has a weird hat which you've previously not been able to muster the courage to wear. If not, what are you waiting for? Go out an buy one for next year's Hat day.

To comply with the recent celebration we put together a list of the best hats in creation.

Hats can be used for several purposes. One is strictly temperature related, to allow an escape from the heat being the most prime example.

Hats are very specialized in conveying a distinctive message: use an unusual hat to make an amazing first impression.

Even celebrities use hats to get noticed in a extravagant, big or colorful way. Even Kate Middleton gets into the action.

Let’s start the countdown, shall we.
