BACK TO SLIDE
While it has always been a huge event in the world of horse racing, the Kentucky Derby has also become quite the event in the world of style. Spectators flock to Churchill Downs, KY every year, eager to watch the horse race, and some perhaps even more eager to show off their creativity.
You've seen our look back at the craziest hats of Derbys past, now we've got the coverage of who attended this year's race. It's a two-day event all culminating in the final two minutes, and the stars who attended weren't afraid to be bold and bright.
