Kate Middleton wore this Princess Diana piece for the G7 summit

The G7 Leader's Summit in Cornwall this weekend was very much a family affair for the royals. The Queen met with Joe and Jill Biden before whisking them away to Windsor Castle for afternoon tea, and Prince Charles and Camilla also attended the even to chat with world leaders such as President Macron.

Prince William and Kate Middleton also descended on Cornwall, and the Duchess even visited a primary school with Jill Biden, as both women are staunch supporters of early education.

For the visit, Kate wore a red Alexander McQueen coat dress, though she later changed into a different outfit for a G7 evening reception at the Eden Project, during which she was reunited with the rest of the family.

This time, she chose a chic white blazer dress, which she accessorised with a piece of jewellery with a special meaning, since it belonged to her late mother-in-law, Princess Diana.

The three-strand pearl bracelet is one Diana wore on several occasions, most notably on her official trip to Hong Kong in 1989.

During that visit, she paired it with her now iconic 'Elvis dress', a moniker she herself came up with for its resemblance to the singer's famous outfits. It was designed by Catherine Walker and adorned with pearls in tribute to the Chinese culture.

She also wore the Cambridge Lover's Knot tiara, which Kate has herself worn several times, usually saving it for very special occasions.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
