Princess Charlotte‘s upcoming christening will surely be a lavish affair — but one member of the royal family will be noticeably missing from the festivities!

Prince Harry won’t be in attendance at his niece’s baptism this Sunday, July 5 because he will be visiting Africa to pursue wildlife conservation work, according to [People](,,2039522220928994,00.html)_. He was also absent for the nearly two-month-old baby’s birth on May 2 as he was touring Australia.

For the occasion, the little princess will likely wear the royal family’s traditional christening gown, which was designed by the Queen’s assistant and a team of dressmakers at Buckingham Palace. The design of the garment is reportedly based on a christening gown commissioned by Queen Victoria in the 19th century.
