ALL HAIL THIS CLASSIC NAIL POLISH COLOR

All hail Essie's Ballet Slippers nail polish, which retails for $9 at drugstores. 

Part of the excitement leading up to the wedding of Prince Harry and Meghan Markle on May 19 is imagining what everyone will wear, especially the bride. 

We can only guess what the Royal family will don for the festivities. But most likely Harry's grandmother, Queen Elizabeth II, will compliment her outfit by wearing Essie nail polish in Ballet Slippers.

Numerous media outlets have reported that's the only brand and color of nail polish the Queen wears. Apparently she discovered the classic pale pink shade 25 years ago and has been a fan ever since.
