Wear Brown Shoes Day is celebrated on December 4th of each year. The staff at National Whatever Day was not able to identify the origin of Wear Brown Shoes Day and have no idea as to why it was established to begin with. We guess someone just really likes brown shoes.
We can only assume that in order to adequately celebrate Wear Brown Shoes Day is to wear brown shoes. We don’t think your brown shoes have to match the rest of your outfit, just as long as your shoes are brown. So, get out there and wear brown shoes.
