A lot of people wear hats. We see people wearing caps or cowboy hats and top hats. Others prefer Dobbs fedora hats which are more their style and sometimes use them with their formal attire. Though the hats are often used to protect the head from the heat of the sun, some wear them even at night to protect their head from the cold night. It sometimes becomes the trademark of a person when he or she always wear a certain type of hat.
