The First Lady, 70, appeared elegant in a bespoke, recycled scarlet dress from Texan designer Brandon Maxwell, teamed with matching high heels.
Dr Jill – who earlier in the day sported a bright pink blazer and white dress for a visit to a Cornish school with the Duchess of Cambridge – first donned the stunning red outfit when attending a Memorial Day service in Virginia in May.
Jill Biden was a vision in red today when joining her husband President Joe Biden for a meet-and-greet with G7 leaders on a Cornish beach for the official start of the summit

It is also the second day in a row that Jill has championed the American designer, having also worn one of his creations on Thursday when she and Joe met Prime Minister Boris Johnson and his wife Carrie.
Bling: Jill also added a $20,700 Panthere de Cartier gold watch to her ensemble
For her look on Friday afternoon, the First Lady added a dainty pearl bracelet to her ensemble, as well as eye-catching golden earrings.
Adding a further touch of glitz, Jill sported bracelets and a matching necklace reading ‘Mama’, before finishing off her look with a $20,700 Panthere de Cartier gold watch, which she wore on her left wrist.
Cartier watches are also favored among the royal family, with Kate Middleton often seen sporting a $4,650 Ballon Bleu De Cartier, which was reportedly given to her by Prince William on their third anniversary.
Meanwhile Meghan Markle has two timepiece designs from the jeweler: a $5,800 Tank Francaise, which she purchased for herself to celebrate Suits being renewed for a third season, and a much pricier $23,000 version of the same watch, which once belonged to the late Princess Diana.

As far as glamour was concerned on Friday, President Biden’s wife, who wore her blonde hair coiffured away from her face, kept her makeup minimal and opted for a fine layering of mascara.
Jill was all smiles as she joined her husband Joe and the other G7 leaders and their spouses, elbow-bumping the Prime Minister upon her arrival.

Earlier today, Dr Jill cut an elegant figure in a white dress and bright pink $625 blazer from California-based brand L’Agence as she arrived to meet with the Duchess of Cambridge, 39, at Connor Downs Academy.
She paired the ensemble with nude heels from Valentino, and wore a pale-colored face mask on her wrist.
The two chatted together as they walked into the school, with Kate matching the First Lady in a £1,125 fuchsia midi dress from Alexander McQueen and a £225 L.K. Bennett handbag.
Dr Jill and Kate heard how the school’s pupils are supported through a bespoke Early Years Foundation Stage (EYFS) curriculum, which uses child-led teaching to help its pupils to develop as independent, confident and successful learners.
Kate wore her bouncy brunette locks styled in her signature side parting and opted for minimal makeup as she sported a simple smoky eye.
Her fuchsia pink dress, which is currently sold out online, is described as perfect for a ‘first date’.

The silk dress, which was made in Italy, appears to have been slightly customised for the Duchess, with a longer hemline and a bold sixties style belt added.
For First Lady Jill, the G7 summit marks the first time she has left the US since husband Joe became president.
In the evening, the Queen and Prince Charles are set to host a reception at the Eden Project for the world leaders and their spouses.
