The unwritten rule of the Kentucky Derby — which costs more to attend than you think — is that you absolutely need to wear a hat — you'll stick out like a sore thumb otherwise and look wildly underdressed for the big event (via My Bucket List Events). Whether you want to go all out with feathers, ribbons, a wide brim, or a bright color, the good news is that you can tailor your hat to your specific style — there's no need to wear something you don't feel comfortable in or doesn't fit your aesthetic. You can even opt for something a little more subtle or chic — as long as you make sure your head isn't naked, you've already got part of your ensemble ready to go.

While many women opt for a spring dress — don't forget that an A-line dress looks good on everyone — women aren't technically required to wear a dress to the event. In fact, many women over the years have donned sleek pantsuits, full-length jumpsuits, and other alternatives in place of traditional garments. If you're lucky enough to be attending the Derby, you might even be rubbing shoulders with celebrities like Kim Kardashian, so you absolutely have to dress to impress. 

As far as shoes and accessories go, you'll want to wear chunky heels, wedges, or even flats, thanks to the cobblestone pathways and grass that make up the majority of the grounds. Pack a clutch and a bigger bag to carry a change of shoes and extra layers in case it gets cold.
