Royal garment worn by Queen Elizabeth, King Charles, Prince William, Prince Harry on display

A garment treasured for over a hundred years is now being showcased at Buckingham Palace, marking its inaugural public display.

A display titled Queen Elizabeth II: Her Life in Style, showcasing more than 300 items from Queen Elizabeth's personal wardrobe, is being held at The King’s Gallery from April 10 to October 18.

The exhibition highlights a variety of outfits, ranging from her wedding dress to her coronation attire, and ensembles worn during meetings with famous personalities, dignitaries, and world leaders.

The collection also includes an extensive range of jewelry, hats, handbags, gloves, and other accessories.

Over half of the garments have never been publicly viewed before, including a notable piece cherished by royal generations: the Honiton christening gown, worn by 62 royal children since Queen Victoria's daughter, Princess Victoria, was christened in 1841.

Styled to mirror Queen Victoria’s wedding attire, the white silk gown was crafted by Janet Sutherland, the daughter of a miner from Falkirk, Scotland.

Queen Victoria later wrote in her journal that both she and Prince Albert were pleased that everything proceeded "beautifully and with dignity."

Displayed at "Queen Elizabeth II: Her Life In Style," the Royal Christening Robe is featured in The King’s Gallery at Buckingham Palace.

Victoria and Albert’s eldest son, the future King Edward VII, was the first in line for the throne to be baptized in the gown.

His successors, his son George V and grandson Edward VIII, who later abdicated, followed this tradition. Queen Elizabeth's father, George VI, alongside her direct successors, King Charles and Prince William, were also christened wearing the gown.

The traditional gown was worn by other royals such as Prince Harry, Princess Beatrice, and Princess Eugenie.

Despite meticulous efforts to maintain its condition — it was delicately cleaned with spring water and stored in a darkened environment after each use — Queen Elizabeth decided in the mid-2000s that it was time to create a replica to preserve the original gown for posterity.

Lady Louise Windsor, now 22, was the final royal baby to wear the original garment, while her younger brother, James, Earl of Wessex, now 18, became the first to don the duplicate gown.

The replica gown has been used for christening a new generation of royals, including the children of William and Kate — Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7.

Experts from the Royal Collection spent 100 hours preparing the gown for exhibition.

Using careful techniques, the textile conservator from the Royal Collection Trust, Cecilia Oliver, repaired minor damages and added “delicate reinforcements to fragile fabric areas.”

Caroline de Guitaut, curator, stated, “The christening gown was the most important infant outfit for Princess Elizabeth and is a remarkable example of British artistry, a legacy Queen Elizabeth upheld through her life.”

“As the earliest garment donned by the Queen, and many royal infants before and after, it holds a cherished spot in her collection. We are thrilled to share it widely during this special centennial year.”
