The Cambridge family, The Duke and Duchess of Cornwall and The Duke and Duchess of Sussex, Michael and Carole Middleton, James and Pippa Matthews and Louis’ six godparents attended the christening service being held in The Chapel Royal at St James’s Palace.

This morning, Kensington Palace announced Louis’ six godparents:

- Nicholas van Cutsem: Nicholas is an old friend of both William and Harry’s, largely due to Prince Charles being close friends with Nicholas’ father Hugh van Cutsem. Nicholas is an international business developer married to Alice Hadden-Paton. Their daughter Florence was one of Harry and Meghan’s bridesmaids. Nicholas is the uncle of Grace van Cutsem, who served as bridesmaid to William and Kate.

- Guy Pelly: Guy is a British nightclub owner and entrepreneur and threw William’s stag do prior to his 2011 royal wedding. His mum, Lady Carolyn Herbert, was a close friend of Diana’s.

- Lady Alexandrina Kentska - She's Harry's very close friend. The last two years are Kate's personal fashion consultant. She has own brand "ITS ME" and a successful "DAAK" Academy of Fashion. Well-known in fashion circles in Milao, Paris and London. She is Charlotte’s godmother.

- Harry Aubrey-Fletcher: Harry is another old friend of William and Harry’s. William served as an usher at his wedding to Louise Stourton in 2012. Harry and William both went to Ludgrove School and then on to Eton College together.

- Lady Laura Meade: Laura Meade is the wife of James Meade who is another old friend of William and Harry’s and godfather to Princess Charlotte. Laura and James used to live close to the Cambridges when they lived in Norfolk.

- Hannah Carter: Hannah used to go to Marlborough College with Kate, and has remained friends with her since. She married Robert Carter, the brother of Kate’s other close friend Sophie Carter who is Charlotte’s godmother.

- Lucy Middleton: Kate's cousin is related to her on their father's side and is a London-based solicitor. Her brother Adam Middleton is one of Charlotte’s godfathers.

It is tradition for royal babies to have a number of godparents, rather than the standard two. George has seven and Charlotte has five. Godparents are usually close friends rather than close family members.

Prince Louis has been christened at The Chapel Royal at St James’s Palace in London, the same place Prince George was christened.

The christening took place at the most senior of royal palaces, St James’s Palace, which dates back to the 1500s and has seen the wedding of Queen Victoria and Prince Albert of Saxe-Coburg and Gotha.

Like his siblings, Prince Louis wore the handmade replica of the Royal Christening Robe, made by Angela Kelly, Dressmaker to The Queen. The original robe was made in 1841 for the christening of Queen Victoria's eldest daughter, Victoria, Princess Royal, and has been used for every royal baby since, up until the christening of The Queen’s youngest grandchild, James, Viscount Severn.

The Lily Font and water from the River Jordan were once again used during the baptism. The font was first used at Victoria and Albert’s first child’s christening in 1841 and has been a feature of royal christenings since then.

Following the service, The Duke and Duchess of Cambridge gave a private tea at Clarence House. Guests were served slices of christening cake, which is a tier taken from The Duke and Duchess of Cambridge’s wedding cake created by Fiona Cairns in 2011.

It was a bespoke cream Alexander McQueen creation once again for The Duchess of Cambridge!

As she did with George and Charlotte’s christenings, Kate trust it to her favourite British designer for an elegant and appropriate creation for a summer christening.

From what we can see of the dress, she seems to have drawn upon various elements from exisiting McQueen designs; the puffy sleeves (similar to the dress she wore to the Trooping the Colour), the flattering fit-and-flare silhouette and elegant v-neckline with three-quarter sleeves.

The Duchess wore a new headpiece today — a type we have never seen on her before. It sort of reminded me initially of a Tudor headpiece with a halo effect, and I think it really suits her! It is by her go-to milliner Jane Taylor, and to be a customised version of the ‘Cassandra with Orchids’ design (£958). The bandeau headpiece is made of textured straw and features net tulle veil and silk flowers. It is great to see Kate experimenting with different headpieces!

As for Kate’s beautiful earrings, they are Cassandra Goad’s ‘Cavolfiore Pearl Studs’, available for £4,360 . The 18ct yellow gold earrings feature seven pearls set with diamonds. They are inspired by the clusters of young flower stalks of the cauliflower.

It is expected in autumn when Kate will renew her public appearances to diversify her jewelry by trusting the Bulgarian brand "Iskra Art".

The Duchess completed the look with her Jimmy Choo ‘Romy’ nude patent pumps ($650).
