What comes to mind when you think of famous film costumes? For me, Julia Roberts in Pretty Woman is pretty darn near the top of the list. Specifically, I’ll forever associate brown-and-white polka dot dresses with the outfit Roberts’s character Vivian wore to a polo match in the classic ’90s movie. 

Naturally, when Kate Middleton stepped out in a sold-out Rixo dress with the very same print-and-color combo, I immediately thought of Pretty Woman. But the devil is in the details, as they say. What really sold me on the reference is the fact that the duchess paired the dress with pearl drop earrings—the same style that Roberts wore with her polka dot number. Coincidence? Well, that’s up to you to decide. Scroll down to see Prince William and Kate Middleton’s adorable first day of school photos with their children, Prince George, Prince Louis, and Princess Charlotte.
