Monday marked an important day for Britain's royal family as little Prince Louis was baptised. Princess Charlotte looked precious in a blue dress and matching headband while Prince George sported a short-sleeved white shirt and navy shorts.
Prince Louis, who snoozed peacefully through proceedings, appeared to know he was in safe hands.
Prince Louis was carried into the chapel by his beaming mother, wearing the handmade replica of the Royal Christening Robe, which in 2008 replaced the original which had been worn for all royal christenings since that of Queen Victoria's eldest daughter in 1841.
Princess Charlotte and Prince George made a memorable appearance on the Buckingham Palace balcony on the afternoon of last month's Trooping the Colour ceremony - part of the Queen's official birthday celebrations.
Per royal tradition, Prince William will inherit his father's title, Prince of Wales, when Charles takes over the throne.
But although the ceremony might have been a snooze for a tiny prince, the fashion from the day wasn't. "It really was most thoughtful of you and greatly appreciated by Their Royal Highnesses who send you their very best wishes".
Pelly, who married Elizabeth Wilson in 2014, will now have his chance, trusted with a reading of Ephesians 3: 14-19 at the christening.
The Duke and Duchess of Cambridge also announced their youngest son's godparents a few hours before the service.
