While the Duchess of Sussex wowed fans at her first formal evening occasion as a member of the royal family in Fiji on Tuesday, royal watchers were asking why newly-pregnant Meghan wasn't wearing a tiara.
Despite being an undeniable rhapsody in blue (the duchess wore a vibrant blue cape dress by Safiyaa and chandelier diamond earrings), her dark locks were devoid of jewels – unlike her sister-in-law who was glittering in Princess Diana's famous Cambridge Lover's Knot tiara at a State Banquet on the same night back in Britain.
Both are duchesses, both were attending state dinners so why could the Duchess of Cambridge dazzle in diamonds but not Meghan?
The answer is simple.
Not that a lack of tiara took the shine off Duchess Meghan's star quality that night. Dare we say she had a new pregnancy glow about her?
With her pregnancy having been announced just over a week ago, Meghan's maternal side was out in full force as she cradled her baby bump while speaking to guests and posing for photos. Fans were quick to point out her growing tummy, which was particularly noticeable in the dress.
One fan took to Twitter to share one of the adorable snaps of Meghan, writing: "Side view tells the full or expanding story."
Meghan wore her hair in falling waves and accessorised her look with some stunning jewellery. Harry also looked dashing in a black evening suit and bow tie.
Like Meghan, it was clear how smitten the Prince was for their new baby - in a touching supportive gesture when the pair went to toast at dinner, Harry joined the Duchess in toasting with water.
Fans on Twitter gushed about the show of support, with one writing: "Nice Good Job Harry Supporting Meg During her pregnancy."
Another wrote: "Aww so sweet of Prince Harry to join her in her 'water toast.'"
The event was hosted by Fijian President, Major General Jioji Konrote and attended by politicians, diplomats and local business leaders, who mingled with the royal couple throughout the soiree.
Despite the high-brow guest-list, Prince Harry couldn't help but share some humour in his speech during the dinner.
Speaking about the royals long-standing relationship with Fiji, the Prince said: "We share Commonwealth values and common goals – a love of rugby and a sense of humour.
"Our ties run deep."
He also paid homage to the Fijian soldiers who had served with British troops over the years.
"I must emphasise my respect, admiration and camaraderie with the Fijian soldiers that I served with in Afghanistan," he told the guests. "We trained together, we fought together, and most importantly we laughed together."
The royal couple's trip to Fiji is particularly special because it almost exactly mirrors a visit Queen Elizabeth and Prince Phillip made in 1953 shortly following her coronation. The Queen and Prince attended a similar ceremony to the one Meghan and Harry attended on Tuesday night.

During his speech, Harry referenced his grandmother's ties to the country: "This visit is particularly nostalgic for us as a young married couple - my grandparents stayed in this very hotel, the Grand Pacific, a number of times over the years."
In another sweet tribute, Meghan wore earrings that were gifted to her by the Queen herself for her arrival in Fiji on Monday afternoon.
And it's not just the Queen who is familiar with the country - many royals have visited Fiji over the years, including Prince Charles who visited in 1970, 1985 and 2005.
Something that delighted President Konrote who said, "Thank you for coming to Fiji and gracing us with your much welcome but very short visit. It's good to know that you promise to come back. May Almighty God be with you now and in the future."
