Pincess Charlotte's christening is to take place on the Queen's Sandringham estate in Norfolk today.
The baptism, conducted by Archbishop of Canterbury the Most Reverend Justin Welby, will be held in private in the same church where Princess Diana - who would have been Princess Charlotte's grandmother - was baptised in 1961.
But members of the public will be allowed into the area outside the church - known as the paddock - to see Charlotte and other royals arrive and depart.
Like her brother, Charlotte will be christened in a replica of the lace and satin christening gown made for Queen Victoria's eldest daughter, Victoria, the princess royal, in 1841.
The original was worn by all royal babies until the christening of Prince Edward's son James, Viscount Severn in 2008.
He and all subsequent royals have worn the replica, commissioned by the Queen to protect the original and made by royal dressmaker Angela Kelly.
Charlotte will be christened using the ornate silver gilt Lily Font from Victoria's reign which is usually on show as part of the Crown Jewels in the Tower of London.
In the presence of her great-grandmother and, as things stand, three future kings - Charles, William and George - Princess Charlotte will be baptised with water from the River Jordan.
Prince William's cousin, Lady Laura Fellowes - the daughter of Baroness Jane Fellowes, a sister of Princess Diana - will be one of Prince Charlotte's godparents.

Prince George will attend his younger sibling's christening
The Duke and Duchess of Cambridge have chosen five godparents for Princess Charlotte, including William's cousin Laura Fellowes.
The announcement was made ahead of the royal baby's christening in Norfolk.
Other godparents include Catherine's cousin Adam Middleton and Thomas van Straubenzee, a friend of the duke's.
The christening will be held on the Sandringham estate and attended by the Queen, other senior members of the Royal Family and Catherine's parents.
The duke and duchess, Prince George and the princess will appear as a family of four in public for the first time at the baptism at the Church of St Mary Magdalene in Sandringham.
The baptism, conducted by Archbishop of Canterbury the Most Reverend Justin Welby, will be held in private.
But members of the public will be allowed into the area outside the church - known as the paddock - to see Charlotte and other royals arrive and depart.
The Prince of Wales and Duchess of Cornwall will both attend the ceremony
Other guests will include the Duke of Edinburgh, Duchess of Cornwall and Catherine's two siblings - Pippa and James Middleton.
Princess Charlotte has two fewer godparents than her brother George.
The final two godparents announced by the family are the duke's friend James Meade and the duchess's friend Sophie Carter.
Mr van Straubenzee, whom William met at Ludgrove Prep School, and Mr Meade, a friend from Eton, were both ushers at the duke and duchess's wedding and gave speeches at the reception.
Lady Laura Fellowes is the daughter of Baroness Jane Fellowes - a sister of Diana, Princess of Wales.
Like her brother, Charlotte will be christened in a replica of the lace and satin christening gown made for Queen Victoria's eldest daughter, Victoria, the princess royal, in 1841.

Norfolk police are expecting large crowds near the 16th century church and have urged people to arrive early for the opening of the paddock gates at 15:00 BST.
The ceremony is due to start at 16:30.
Superintendent Kevin Clarke said: "With this being such a special occasion we are expecting the area to be extremely busy on Sunday and encourage the public to heed our advice so they can enjoy the event safely."
'Hugely grateful'
Anyone bringing flowers will be asked to give them to representatives of East Anglia's Children's Hospices, where Catherine is a patron, who will then take them to hospices in the region.
A Kensington Palace spokesman said: "The duke and duchess are hugely grateful for the warm wishes they have received since Princess Charlotte's birth - many of them from local people in Norfolk - and are delighted the paddock can be opened on the day of the christening."

Prince Harry will be among those missing from the ceremony. He is currently spending three months in Africa.
St Mary Magdalene is the church used by the Queen when she is resident on her private estate.
Archbishop Welby will give an address. He will be supported by The Reverend Canon Jonathan Riviere, the Rector of the Sandringham group of parishes.
Mario Testino has been asked by William and Catherine to take the official photographs after the service.
Following the service, the duke and duchess will host a tea at Sandringham House where guests will be served slices of christening cake, which is a tier from their wedding cake.

In the presence of her great-grandmother and, as things stand, three future kings - Charles, William and George - Princess Charlotte will be baptised using a font from Victoria's reign and with water from the River Jordan.
The Church of Saint Mary Magdalene is where the royals usually gather on Christmas Day and where Charlotte's late grandmother - Diana, Princess of Wales - was christened.
It's been chosen because it is close to Anmer Hall, William and Kate's second home. This Norfolk retreat is where they intend to bring up their family.
In the congregation, witnessing the start of the nine-week-old baby's spiritual journey, will be members of her family and close friends of her parents.
Babies, royal or otherwise, react differently to this moment of celebration.
The Queen cried so much during her baptism in 1926 that her nurse had to give her a dose of dill water.
