Women (and men) wear hats at the Kentucky Derby as part of a long-standing tradition that dates back to the event's inception in 1875. The hats symbolize elegance, sophistication, and the grandeur of the occasion, reflecting the Derby's origins as a high-society social gathering. The tradition also allows attendees to express their personal style, creativity, and have fun with fashion, making the hat a central and iconic accessory of the event. Moreover, large hats also serve a practical purpose in providing shade from the sun during the outdoor event. This blend of history, fashion, social status, and practicality has made hats an enduring and celebrated part of Kentucky Derby culture.
