Prince George attends Trooping the Colour in one of dad Prince William's old outfits

Astute royal fans were quick to recognize Prince George's adorable outfit when he was carried out onto the balcony on Saturday (June 11) for his great-grandmother's birthday celebration.

The tot had borrowed one of his dad Prince William’s old outfits – the royal had worn it to attend his brother Prince Harry’s christening in 1984. He also wore it for the Trooping the Colour in 1986.

The two-year-old looked cute in the white shirt and blue shorts. With a bit of encouragement from his dad, the handsome little boy waved to the waiting crowds before shyly turning away.

His sister Princess Charlotte, meanwhile, looked equally gorgeous in a cute pink dress. The 13-month-old clung to her mom Kate as she was carried out onto the balcony.

Kate was wearing the same outfit as earlier on in the day – a white Alexander McQueen coat and a pink Philip Treacy hat.

The coat was recycled – she previously wore it for the christening of Princess Charlotte. Her gorgeous hat, a new headpiece for Kate, was beautifully tilted and featured a large flower beneath the brim.

Making sure the hat took centre stage, Kate kept her glossy locks in a chic chignon. At Princess Charlotte’s christening, Kate had chosen to pair the elegant Alexander McQueen coat with a white pillbox hat.
