Felt Hat Day is observed on September 15, 2025. On this day everybody, regardless if man or women, is encouraged to wear a felt hat. The hat can be big or small, colorful or uncolored, fancy or simple. There is only one rule: it has to be a felt hat. Hats were a popular garment and had an important role in fashion and attitude, and felt was a common material for hats in the 1900s. So if you have hidden somewhere an old felt hat from back then, today is your chance to pull it out and show everybody that you celebrate Felt Hat Day.
