Prince Louis Steals the Show at Westminster Abbey Christmas Carol Service

Prince Louis, the youngest member of the royal family, made a delightful debut at the Westminster Abbey Christmas Carol service, capturing the hearts of royal fans.

In a rare public appearance, the three siblings – Prince George, Princess Charlotte, and Prince Louis – attended the festive event, adding to the excitement of the evening.

Observers couldn't help but notice how quickly 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 displayed his charming personality by offering his hand for a handshake and expressing gratitude afterward.

This heartwarming moment showcased the young prince's growing independence, leaving his parents, William and Catherine, feeling immensely proud.

However, sibling rivalry was on full display after the service.

Mischievous as ever, Prince Louis cheekily blew out his sister's candle, causing laughter among the royal family.

Despite Charlotte usually keeping her younger brother in line during royal outings, she seemed to let him have his fun on this occasion.

This isn't the first time that Prince Louis has stolen the spotlight.

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

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

Say King!

Yay King!”

His absence from the coronation concert, due to bedtime, didn't go unnoticed either, as fans wondered where the adorable prince was.

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

He has become quite the fashion icon, too, as he sported a navy blue jacket with a maroon-colored jumper underneath.

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

However, it was the choice of trousers that caught the public's attention.

Traditionally, royal boys wear shorts at royal engagements until they turn eight.

This practice, according to etiquette expert William Hanson, has now been relaxed for Prince Louis.

Previously, his older brother George adhered to the tradition, but Louis's appearance in long trousers suggests a shift in the monarchy's approach.

Royal expert Richard Fitzwilliams commented on the evolving traditions within the royal family, stating that while it was once customary for upper-class boys to wear shorts, it is no longer a strict rule.

Fitzwilliams emphasized that children should have the freedom to choose their clothing, and if Louis prefers long trousers, he should be allowed to wear them.

Prince Louis's charming presence at the Westminster Abbey Christmas Carol service not only delighted royal fans but also highlighted the young prince's growing independence and evolving fashion choices.

As he continues to capture hearts on royal outings, it is clear that Prince Louis is carving his own path within the monarchy.
