The dress Princess Anne wore in her portrait, however, may look a bit familiar. If so, great eye—as Rachel Bowie, senior director of royals and special projects, first reported, Queen Elizabeth’s daughter wore the outfit this past June, when she attended a reception at Windsor Castle in honor of the King’s Foundation.

As Bowie noted, Princess Anne kept her jewelry minimal—no tiaras, ornate brooches or three-string strands of pearls here. Even the outfit repeat feels deliberate. “If there’s one core message that has been delivered by the palace leading up to this milestone occasion, it’s that there will be zero. fuss. made. Yes, the Royal Mint dropped a new coin, but other than that, her intention is to spend the day as she always does: Sailing around western Scotland with her husband, Sir Timothy Laurence. And that’s that,” Bowie shared.
