On the eve of the Royal Wedding, while Prince Harry and Meghan Markle were enjoying their rehearsal dinner, we attended our own rehearsal dinner at the Plaza Hotel in New York City, hosted by etiquette expert and Royals enthusiast Myka Meier! Myka tells us about how Meghan will not only have to adjust her posture but also her vocabulary to fit in at the palace. You can follow Myka on Twitter and Instagram @MykaMeier, and if you are in New York City you can schedule an etiquette course with Myka through the Plaza Hotel!Check the feed later today for our Royal Wedding Recap!See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
