Sophie, Duchess of Edinburgh, Wore Her Beloved Aquamarine Tiara at the German State Banquet

ophie, Duchess of Edinburgh, joined the British royal family at Windsor Castle on Wednesday evening for a state banquet honoring German President Frank-Walter Steinmeier and First Lady Elke Büdenbender. The Duchess leaned into a classic look for the event, pairing her favorite tiara with the Debutante Floor Length gown by Suzannah London. Sophie has worn the Aquamarine Tiara many, many times over the years, most recently at the French state banquet in July.

The slender black frock is part of Suzannah London’s Atelier Collection. Per the label, the design was “inspired by 1950s elegance” and “features a sculpted architectural collar, a structured bodice and elbow-length sleeves, flowing into an A-line skirt with a subtle back train to create a refined, statuesque silhouette.”

The Duchess of Edinburgh also wore her yellow ribbon with the Royal Family Order of King Charles III, which she received in July ahead of the French state visit. Royal Orders are traditionally given to senior women of the royal family in recognition of their service to the monarch. The Duchess completed her elegant ensemble with her Royal Sash and Star.

Sophie went with a white gown and the same tiara during the summer.

State banquets often bring out a parade of flowing gowns and glittering tiaras from the royals. Also in attendance at Windsor this evening included Queen Camilla in the Girls of Great Britain and Northern Ireland tiara, the Princess of Wales and the Orient Circlet tiara, Princess Anne with the Aquamarine Pineflower tiara, and the Duchess of Gloucester in Queen Mary’s Honeysuckle tiara.

The event marked a notable return for Sophie as both she and Prince Edward missed the last state banquet in September held on behalf of U.S. President Donald Trump and First Lady Melania Trump. The couple were already in transit to Japan to represent King Charles on an official visit to Tokyo and Osaka.
