Despite serving in the British Army for 10 years, Prince Harry has been wearing civilian attire at all public ceremonies since the death of his grandmother, the Queen.
The Duke of Sussex stepped down as a working member of the Royal Family to start a new life in the US in 2020 with Meghan Markle, therefore rescinding the right to wear his uniform at official events.
When the Queen's casket was carried from Buckingham Palace to Westminster Hall to lie in state on Wednesday, he wore a morning suit.
In contrast, his brother Prince William, aunt Princess Anne, uncle Prince Edward and father King Charles III, all wore military uniform as they marched behind the coffin along the Mall in central London.
Harry is also not expected to be allowed to wear his uniform for his grandmother's funeral service at Westminster Abbey on Monday.
However, he will be dressed in full uniform at a vigil involving the Queen's grandchildren on Saturday, after palace officials had a change of heart and gave him the green light as a special exception.
Throughout all of these events, Harry has been allowed to display the medals he has been accorded over the years.
What medals does Prince Harry have?
Harry served the British Army for 10 years and saw action on the front line during two tours of duty in Afghanistan.
In 2008 he received the Operational Service Medal for Afghanistan in recognition of his service in Helmand Province.
He also has the Knight Commander of the Royal Victorian Order (KCVO), which was given to him by the Queen in 2015 for 'services to the sovereign'.
The duke also has the Queen's Golden Jubilee Medal, awarded in 2002 to all of those in active service who had been in the Armed Forces for five years.
In 2012 Harry was awarded the Queen's Diamond Jubilee Medal, which was given to all of those in the emergency services, Armed Forces, prison service and the Royal Household.
This year he received the Queen's Platinum Jubilee Medal - mostly reserved for serving Armed Forces or frontline service workers - despite the duke giving up his honorary military titles in 2020.
On Monday, Harry wrote of his special memories of the Queen attending his passing-out parade in 2006 when he became an officer in the British Army.
He told of his 'first meeting' with his grandmother as 'my Commander-in-Chief', and was thought to have been referring to the occasion she made him grin and blush when she reviewed the cadets.
