The use of hats has been traced as far back as Ancient Egypt, when upper-class Egyptians would shave their heads and subsequently wear headdresses to keep them cool. Indeed, from its functional protection from the weather to its indication of social status, the hat has become an integral part of various cultures throughout history. They have been given special meanings, special occasions, special religious significance, and even shape-shifted into fashion statements. They're made from cotton, wool, straw, fur, felt, and much more, and the shapes, colors, and features tell us so much about different types of people, places, and times.
