Following tradition, royal ladies typically wear tiaras for the first time on their wedding day. Princess Charlotte, who is only 8 years old, will not see that day for more than a decade, but her tiara-wearing debut may be earlier than the other women in the royal family, according to a report in People. (We already got a glimpse of Charlotte in a tiara at Prince Charles' coronation last May, when a Jess Collette x Alexander McQueen headpiece showed the mother princess in silver bullion, crystal, and silver threadwork embroidered with three-dimensional leaves.) [Even the royal blood relatives, including Queen Elizabeth's granddaughters, Princess Beatrice, Princess Eugenie, and Zara Tindall, made their tiara debuts on their wedding day. Nevertheless, Charlotte "may be able to wear a tiara from the royal vaults before she walks down the aisle," People reports.

This is not without precedent: both Princess Anne, the late Queen's only daughter, and Princess Margaret, the late Queen's sister, wore tiaras before their weddings. Anne "first wore a tiara as a teenager, and even before her wedding to Mark Phillips in 1973, she wore tiaras on white-tie occasions such as state dinners and palace receptions," People reports. "For example, she wore Cartier's Halo Tiara (worn by Kate on their wedding day in April 2011) for the opening of Parliament in 1967, and in 1969, Princess Anne wore another statement head-topper (Princess Andrew's Meander Bandeau) for an official visit to Austria accompanied her mother, wearing a "Kate".

Princess Anne, who first married in 1973, wore Queen Mary's fringe tiara, which her mother Queen Elizabeth also chose for her wedding to Prince Philip in 1947.

"Princesses Anne and Margaret, who died in 2002, were able to wear tiaras to the gala event leading up to their wedding because, unlike the women who married into the royal family and Queen Elizabeth's granddaughters, they worked for the royal family," People wrote.

"Princess Charlotte is the granddaughter of King Charles, daughter of Prince William, heir to the throne, and sister of the future monarch, Prince George.

After the death of Queen Elizabeth last September, Europe now has only one reigning female monarch, Queen Margrethe of Denmark, but that will change in the next generation. Princess Ingrid Alexandra of Norway, Princess Katharina-Amalia of the Netherlands, and Princess Elisabeth of Belgium are all heirs to the throne, and all three made their tiara debuts before their marriage at Ingrid Alexandra's 18th birthday celebration last summer. At that time, Katharina-Amaria was also 18 and Elisabeth was 20, setting a precedent for Charlotte to make her tiara debut before her wedding.

Her mother adored Queen Mary's Lover's Knot tiara, which was also worn by her late mother-in-law, Princess Diana. In addition to the Cartier Halo tiara she wore at her wedding, Queen Mary's Lover's Knot tiara is the only tiara, aside from the Lotus Flower tiara, that Kate has worn in her 12 years as an active member of the royal family. This summer was the first time Kate wore a tiara outside of the UK, when she wore it to the royal wedding of Crown Prince Hussein and Princess Raja in Jordan.
