The Kentucky Derby has a red carpet like none other in the world. While the annual horse-racing event originated as an opportunity for Southern attendees to show off the latest spring fashions, today more often than not women eschew contemporary trends for more traditional looks, complete with pretty dresses and statement-making hats, with eclectic twists. Hats have been a signature of the Kentucky Derby since the beginning, as a symbol of good luck, but over the years the hats have become more and more elaborate. Celebrities and spectators alike take their looks very seriously, preparing months ahead of time, wearing custom made hats and fabulous fascinators, depending on where they are seated: traditionally, guests in the seated sections of Churchill Downs prefer more elegant styles, like wide-brimmed hats, while those in the Infield traditionally wear hats that are a bit more eccentric and themed, like a fascinator. Colorful and floral, spring dresses are also a staple fashion at the Derby, having come from the desire to create a rainbow sea to anyone looking into the crowd. From southern bells to famous faces, here’s a look at how Kentucky Derby fashion has changed through the years.
