Prince Harry is among the small group of royals who will be in attendance at Prince Philip's Saturday funeral, and apparently there's some concern about what he'll wear. Because Harry was stripped of his honorary military titles as a result of stepping down from royal duties, there's been speculation that he'll have to wear a suit to his grandfather's service. Meanwhile, The Sun reports that Prince William, Prince Edward, Princess Anne, and even the disgraced Prince Andrew, are all expected to wear regimented attire—potentially making Harry the odd one out.
The royals obviously don't want any tension during Philip's funeral, and there are theories that William could wear a suit to match his brother, or—per The Sun—that Harry could potentially be allowed to wear a "basic" military uniform due to his years of service. However, it's ultimately up to the Queen—who's expected to decide what each member of her family will wear to the funeral in the next few days.
Either way, Harry is said to be solely focused on his grandmother's wishes right now. A source tells The Telegraph (via The Daily Mail) that "[Prince William and Prince Harry] know it is not about them on Saturday—it is about honouring their grandfather's memory and supporting their grandmother. I would be extremely surprised if that wasn't front and centre of both their minds. They will be keen to spend time together as a family, in the same time zone for once."
That said, the brothers are not expected to see each other ahead of Saturday's funeral service, though they have spoken on the phone. Meanwhile, Prince Harry is expected to fly home to Meghan Markle and Archie the day after Philip's funeral.
