Princess Kate didn't curtsy to King Charles at a recent event, sparking renewed interest in the tradition on social media.

Royals are expected to curtsy or bow once a day to the King and Queen consort.

Kate's lack of curtsy suggests she may have greeted her father-in-law earlier in the day.

Commonwealth Day is an official holiday celebrating the Commonwealth of Nations.

The day includes a service at Westminster Abbey attended by senior members of the Royal Family.

Kate looked stunning in an Erdem peplum jacket and matching skirt, navy pumps, and an embellished hat at the event.

She wore a Prince of Wales feathers brooch, a gift from the King.

Despite the controversy, Kate's style continues to inspire fans around the world.

Her grace and dedication to duty reflect her unwavering commitment to her country and future role as queen consort.
