Prince George and Princess Charlotte's christening gown going on display

An exhibition at Buckingham Palace this summer will showcase the christening gown worn by both Prince George and his younger sister Princess Charlotte. Starting on July 23, visitors will be able to have a closer look at the spectacular lace garment, a must-see in the special collection titled 'Fashioning a Reign: 90 Years of Style from The Queen's Wardrobe.'

The white lace and silk-satin gown is a replica of the one worn by the month-old Princess Elizabeth in 1926. It was commissioned by Queen Victoria for her first child in 1841, and was worn by over 60 royal babies up until 2004, when it became too fragile to wear. The Queen then commissioned her personal dresser Angela Kelly to create an exact replica, which was first used in 2008 for the christening of James, Viscount Severn, and which will be featured in the Buckingham Palace display.

Other key items in the exhibit include the Queen's beautiful ivory silk wedding dress from her 1947 marriage to Prince Philip, and the embroidered satin gown she wore for her coronation at Westminster Abbey in 1953. More recent pieces include the vivid green wool crepe and silk dress and coat she chose for Trooping the Colour in June 2016.

Also on display for the first time are the outfits used for the Queen's unexpected and memorable role in the opening ceremony of the London Olympics. Two beaded peach cocktail dresses were created by Angela Kelly for the spectacle – one for the monarch, and one for her stunt double – and both will be on show.
