See Kate Middleton's Perfect Curtsy to the Queen on Easter with Prince William and Royal Family

Kate Middleton showed off a perfect curtsy once again!

The Duchess of Cambridge attended Easter services on Sunday, April 21, with the royal family and Queen Elizabeth, dressed in an elegant light blue coat and dress with a matching fascinator. Before the service at St. George’s Chapel with husband Prince William, Kate — now a pro at royal protocol — had a moment with the Queen, putting on a model curtsy.

With one foot behind the other, Kate bent her knees and smiled at the Queen, while also slightly bowing her head — exactly how Myka Meier, founder and director of Beaumont Etiquette says a curtsy should look.

Last year, Meier told PEOPLE that a curtsy should be subtle and that the deeper and longer you pause shows more respect and formality.

Kate’s etiquette did well, as today is also the Queen’s actual birthday!

The long-reigning monarch celebrated her 93rd birthday on Sunday and wore a light blue coat and hat that included a bright pink ribbon, matching her dress.
