A hat is a head covering. It may be worn for protection against the elements, for religious reasons, for safety, or as a fashion accessory. In the past, hats were an indicator of social status. In the military, they denote rank and regiment.
But I think, having these hats, it will look you silly when wearing this in public or in streets. I give merit to the designer of these fabulous hats. They look weird but incridible.
