The Kentucky Derby banned silk purses since 1904

Since 1904, the Kentucky Derby has reportedly banned silk purses, a peculiar tradition highlighting the race's meticulous attention to detail. While the exact reason remains obscure, it likely ensured formality and uniformity at America's premier horse race. This rule is part of a rich history of traditions, including colorful jockey silks, that safeguard the Derby's cultural heritage. From its $1,000 inaugural prize to over $3 million today, the focus remains on tradition, not just the purse.
