Prince William and Catherine, the Duke and Duchess of Cambridge, recently met with President Yoon Suk-yol and the First Lady of South Korea during their state visit to London.

The royal couple looked elegant and sophisticated for the occasion, with Prince William donning a dark navy suit and a red silk tie, while Catherine wore a stunning red dress designed by Catherine Walker, complemented by a hat created by Jane Taylor.

As is customary when meeting members of the royal family, there is a display of respect and courtesy.

Men typically bow their heads, while women perform a curtsy.

Cameras captured a heartwarming moment at the Horse Guards Parade ceremonial welcome, where Catherine Beeming, the Princess of Wales, gracefully curtsied to King Charles and Queen Consort, making it her first official curtsy since her father-in-law's coronation and the start of his reign.

This touching gesture left many viewers emotional, with one person commenting on the elegance and loyalty displayed by Catherine, calling her a wonderful future queen.

Despite her high-ranking position within the royal family, Catherine still adheres to strict protocol.

According to etiquette, individuals addressed as His or Her Highness are not required to curtsy or bow to each other.

However, they must show respect to His Majesty, the King, or Her Majesty, the Queen.

During a Christmas carol service last year, body language expert Judy James analyzed Catherine's curtsy to the King and Queen Consort, noting that it showcased the unity and closeness of the family.

James also observed a warm interaction between Queen Camilla and the Princess of Wales, with Camilla placing her hands on Catherine's shoulders in a gesture of affection.

At the Garter Day celebration, an event honoring the Order of the Garter, Catherine supported the royal family from the sidelines.

As King Charles and Queen Camilla passed by in their regal attire, Catherine gracefully curtsied, maintaining her balance with poise and precision.

Alongside Sophie, the Duchess of Edinburgh, she curtsied once more, while Prince William and Prince Edward nodded their heads in a bow.

The body language expert noted the warm exchange between Prince Charles and Prince William, with the latter's comment eliciting a wry smile from his father.

The Duke and Duchess of Cambridge continue to fulfill their royal duties with grace and dignity, representing the monarchy at various events and engagements.

Their commitment to upholding tradition and protocol is evident in their interactions with other members of the royal family.

Catherine's curtsies and Prince William's bows serve as demonstrations of respect and honor, reflecting their roles as future leaders within the monarchy.

In conclusion, the meeting between the Duke and Duchess of Cambridge and President Yoon Suk-yol and the First Lady of South Korea was marked by elegance and respect.

Catherine's curtsy to the King and Queen Consort during the ceremonial welcome left a lasting impression on viewers, showcasing her grace and loyalty.

Despite her high rank, Catherine adheres to protocol, demonstrating her commitment to royal traditions.
