The Duchess of Sussex made a minor fashion faux pas yesterday when she arrived in Tonga in a striking red dress.

Pregnant Meghan Markle, 37, still had the label hanging from her Self Portrait dress as she walked along a red carpet to the sounds of local singers wearing grass skirts at Fua'amotu Airport in Nuku'alofa, the country's capital.

The £345 (NZ $650) bright red floral dress, which mirrored the colour of the Tongan flag, was accompanied by a Christian Dior Clutch and Manolo Blahnik BB pumps, reports the Daily Mail.

But the returns tag remained on her outfit, and did not appear to be immediately noticed - remaining there for at least five minutes as she was being introduced to a party at the airport following their 90-minute flight from Fiji.

Despite making the rare fashion faux pas with the label - which said "returns will only be accepted if this tag remains attached" - the mother-to-be looked radiant in red, holding hands with her husband Prince Harry.

The royal couple were welcomed to the country by Her Royal Highness The Princess Angelika Latufuipeka, the only daughter and eldest child of King Tupou VI and Queen Nanasipau'u Tuku'ah.

Later on Meghan dazzled in her third outfit of the day - an elegant white full-length evening dress by Theia Couture - as the couple dined with the Tongan royals. Afterwards they attended an official reception and dinner.

It came on the tenth day of Harry and pregnant Meghan's 16-day tour of Australia, Fiji, Tonga and New Zealand - and hours after the Duke had been unveiling a memorial for a British-Fijian soldier who died at the Battle of Mirbat.

Queen Nanasipau'u Tuku'ah became Tonga's High Commissioner to Australia when her father became King.
