NEED TO KNOW

Peter Phillips is set to tie the knot with Harriet Sterling on June 6
While the wedding is set to be an “intimate occasion,” there’s still speculation about what the bride may wear

With a royal wedding fast approaching, there is plenty of speculation about the pomp and circumstance surrounding Peter Phillips’ nuptials to Harriet Sperling.

A friend of the couple’s recently told Hello! magazine that, despite involving many members of the royal family, the June 6 wedding is being planned as an “intimate occasion.”

After all, Peter, 48, the eldest grandchild of the late Queen Elizabeth, has lived his life largely out of the royal spotlight and holds no official titles.

Additionally, this is the second wedding for both Peter and Harriet, 45. He was married to Autumn Kelly from 2008 to 2021, and the pair shares two daughters: Savannah, 15, and Isla, 14. Meanwhile, Harriet was previously married to fitness instructor Antonio St. John Sperling, with whom she shares a daughter, Georgina, 13.

Even if it is a lower-key affair, there is still plenty of speculation about Harriet’s style choices. Traditionally, the bride will accent her wedding gown with jewelry from the royal vault, including a tiara.

Peter’s mother, Princess Anne, the Princess Royal, has multiple tiaras in her personal collection that she could potentially loan to Harriet.

The Festoon Diamond Tiara was a personal gift to Princess Anne — unlike many royal tiaras, which are passed down through generations. She received it from the World Wide Shipping Group of Hong Kong in 1973 when she christened one of their ships, and it quickly became a personal favorite.

The Princess Royal wore the tiara in her 1973 engagement photoshoot with her first husband, Mark Phillips, the father of Peter and his younger sister, Zara. She has continued to wear it throughout the years, often pairing it with a festoon necklace she received from her parents, Queen Elizabeth and Prince Philip, for her 18th birthday.

However, despite the tiara’s status as a favorite of the Princess Royal, 75, it is perhaps the least likely to be loaned to Harriet on her upcoming wedding day. Princess Anne previously loaned it to Peter’s first wife, Autumn Kelly, to wear for their May 2008 nuptials.

Another possibility from Princess Anne’s personal collection is an artifact of her Greek royal heritage, as the Meander Tiara was passed down by Prince Philip’s mother, Princess Alice of Battenberg, to her daughter-in-law, then-Princess Elizabeth, on the occasion of her 1947 wedding to Philip.

Queen Elizabeth never wore the tiara publicly, instead gifting it to Princess Anne on her 18th birthday in 1968. The Princess Royal has worn it frequently over the years and proved its special significance to the family when she loaned it to her daughter, Zara, for her July 2011 wedding to Mike Tindall.

Princess Anne also has the Pineflower Aquamarine Tiara, which entered the royal family as an anniversary gift from King George VI to his wife, Queen Elizabeth. The Queen Mother then gifted it to Anne, her granddaughter, on her 1973 wedding day to Mark Phillips.

Princess Anne has had the tiara modified over the years, removing stones to create complementary earrings and brooches, but she has frequently worn it to state dinners in recent years, including those welcoming leaders from Jordan, Germany and the United States. However, the Pineflower Aquamarine Tiara has yet to be worn by a royal bride.

While there are other headpieces in the collection that royal brides have borrowed for their wedding days, there’s also a high possibility that Harriet will forego a tiara completely for her walk down the aisle.

Queen Camilla chose not to wear a tiara for her 2005 nuptials to the future King Charles. Like Peter and Harriet, it was a second wedding for both Charles and Camilla, who tied the knot in a civil ceremony followed by a religious blessing, rather than a more elaborate church ceremony.

Instead of a tiara, Camilla sported a golden feathered headpiece by Philip Treacy.

Peter and Harriet’s upcoming royal wedding will also be without some notable members of the royal family. Princess Anne, her husband, Vice Admiral Sir Timothy Laurence, Zara and Mike Tindall, King Charles, Queen Camilla, Prince William, Kate Middleton, Prince Edward, and Sophie, are all expected to be in attendance. However, Prince Harry, who was close with his cousin growing up, was not invited, a friend recently told Hello! magazine.

“Peter and Harry haven’t spoken for several years and have simply lost touch, so he hasn’t been invited,” the friend said.

Spokespeople for the Duke of Sussex, 41, and Peter had no comment when reached by PEOPLE.

Additionally, Hello! reported that the former Prince Andrew and Sarah Ferguson were not among the invited guests for the nuptials, with a friend of Peter and Harriet’s saying their presence would be a “distraction” amid their legal issues and renewed interest in their ties to Jeffrey Epstein.
