The history of the gown Prince Louis will wear to his royal christening

Prince Louis will wear an outfit steeped in royal history during his christening in London on July 9.

The 11-week old prince will be dressed in the Royal Christening Robe, worn by his siblings Prince George and Princess Charlotte, at their own baptisms.

The elaborately decorated garment, made of fine Honiton lace lined with white satin, is a replica of the gown made in 1841 for Queen Victoria's eldest daughter, Victoria.

The gown was styled after the wedding dress the Queen had worn for her marriage to Prince Albert the year before.

The Victorian gown entered the record books, having been worn by 62 babies during its lifespan, including Queen Elizabeth during her christening at Buckingham Palace on May 26, 1926.

It was also worn by Prince Louis' father, Prince William, during his own baptism at Buckingham Palace in 1982.

But the gown is now so fragile it was decommissioned and a replica made for subsequent royal babies.

Lady Louise Windsor, daughter of the Earl and Countess of Wessex, became the last royal baby to wear the original gown.

Her brother James, Viscount Severn, and Lady Louise's brother, was the first to wear the replica robe in 2008, at Windsor Castle.

The Queen's dressmaker, Angela Kelly, hand-made the replica gown to preserve the original.

Prince Louis' mother, the Duchess of Cambridge, is likely to wear an outfit to compliment the frilly, cream gown as she has done at the christenings of her other children, Prince George and Princess Charlotte.
