Prince Louis, the youngest member of the royal family, made his debut at the Westminster Abbey Christmas Carol service, much to the delight of royal fans.

The three siblings – Prince George, Princess Charlotte, and Prince Louis – made a rare public appearance at this festive event.

Observers couldn’t help but notice how much Louis has grown, as he now stands nearly as tall as his older brother and sister.

Arriving hand in hand with his father, Prince William, Prince Louis showcased his charming personality by offering his hand for a shake and saying thank you afterwards.

It is clear that Prince William and Catherine must be immensely proud of their youngest child, who is growing up so fast.

However, after the service, a mischievous sibling rivalry seemed to take hold in the royal household.

Prince Louis cheekily blew out his sister’s candle, leaving both his sister and mother, Catherine, in fits of laughter.

Despite usually keeping her younger brother in check during royal outings, Princess Charlotte didn’t seem to mind his antics this time.

This is not the first time that Prince Louis has stolen the show.

As the fourth in line to the throne, he has captured attention on numerous occasions.

At the coronation, he melted hearts as he cheered for his grandfather, King Charles, exclaiming, “Yay, say King!

Yay, King!”

However, he had to miss the coronation concert as it was past his bedtime, which sparked curiosity among fans.

Prince Louis has also been photographed pulling faces at the late Queen’s Platinum Jubilee and shushing his mother during the Platinum Pageant.

His playful nature and adorable moments have endeared him to the public.

In terms of fashion, Prince Louis proved to be quite the trendsetter at the Christmas Carol service.

He wore a navy blue jacket paired with a maroon-colored jumper underneath.

Completing his outfit were matching trousers and navy blue Chelsea boots.

It was the choice of trousers that caught the public’s attention, as he had previously been seen wearing shorts at royal engagements.

According to etiquette expert William Hansen, dressing young boys in shorts is a traditional English practice.

Trousers are reserved for older boys and men, while shorts serve as a silent class marker.

However, Prince Louis’ appearance in long trousers suggests a departure from tradition.

Royal expert Richard Fitzwilliams noted that even if there was a rule for royal boys to wear shorts until the age of eight, Louis’ attire signifies the evolving nature of the monarchy.

As fans shared their amusement online, it became evident that Prince Louis’ transition to long trousers has been met with positivity.

It seems that tradition has been relaxed for the young prince, and his fashion choices reflect the changing times.

The monarchy embraces new customs and allows its members, even the youngest ones, to express their personal preferences.

In conclusion, Prince Louis stole the spotlight at the Westminster Abbey Christmas Carol service with his cheeky antics and adorable moments.

As he continues to grow, he captivates the hearts of royal fans and demonstrates the evolving nature of the monarchy.

With his charming personality and stylish fashion choices, Prince Louis is undoubtedly a star in his own right.
