Leaders of the world's seven biggest economies have descended on the quiet seaside region of Cornwall in the UK for the G7 summit, which got under way on Friday.

On the first day, leaders and their partners were greeted with a reception from members of Britain's royal family, including Queen Elizabeth II.

Away from political discussions, Saturday was another packed day, with a Royal Air Force fly-past, a theatre visit and a special appearance from British Prime Minister Boris Johnson's one-year-old son, Wilfred.

The packed day meant a few outfit changes for politicians and first ladies. Carrie Johnson, wife of Boris Johnson, donned her husband's party colours for a meeting on Saturday with world leaders including South African President Cyril Ramaphosa, Moon Jae-in, President of South Korea, and his wife Kim Jung-Sook at The Carbis Bay Hotel in Cornwall.

The tailored bright-blue suit, by British designer Amanda Wakeley, was yet another rental for Johnson, who also opted to borrow clothes from My Wardrobe HQ for the first day of the summit. On Friday, she wore a floral maxi dress from The Vampire's Wife, alongside a yellow Gucci handbag and yellow Prada slingbacks, all of which were rented for the occasion.

It's not the first time she has been known to rent outfits for big events. In May, the same company loaned her the white Christos Costarellos bridal gown she wore for her wedding to Johnson.

On the second day of the summit, leaders and their partners gathered for a special fly-past from the Royal Air Force's Red Arrows. Johnson swapped her blue power suit for a more relaxed floral maxi dress, although kept with the blue colour theme. She paired the dress with metallic flats.

First lady Jill Biden wore a custom-made white dress with a statement butterfly print from Brandon Maxwell for the occasion, wrapping a royal blue shawl around her shoulders.

Wife of French President Emmanuel Macron, Brigitte, chose a more glamorous look for the afternoon, opting for a black funnel-necked, long-sleeved dress from Louis Vuitton – her favoured label.

Earlier in the day, the three ladies also joined together for a visit to the open-air Minack Theatre, where they met and chatted with a number of young performers.

For that visit, the first lady recycled an asymmetric midnight-blue floral dress by Oscar de la Renta, an outfit she also wore last November when she joined her husband on-stage for a rally in Delaware.

Macron kept to her preferred neutral palette scheme, teaming a tailored, tan suit with a cream lace blouse and cream wedges.

On Friday, the queen, Prince Charles, the Duchess of Cornwall, and the Duke and Duchess of Cambridge, gathered at Cornwall attraction the Eden Project to welcome the G7 leaders to Britain.

The three-day summit is expected to end with an agreement to share one billion vaccine doses around the world by the end of 2022.
