The Prince and Princess of Wales surprise well-wishers in Windsor

The Prince and Princess of Wales were all smiles as they made a surprise walkabout in Windsor on Sunday afternoon.

Beaming from ear to ear, the royal couple paused to shake hands and chat with concert-goers lining the Long Walk ahead of the star-studded coronation concert taking place this evening. 

For the special occasion, Princess Kate looked lovely wearing a powder blue jacket, a white T-shirt and a pair of ultra-flattering tailored trousers. She accesorised with pearl drop earrings and slipped on a pair of stylish Veja trainers.

Take a look at the moment the royal couple surprised fans in the video below...

She wore her glossy chestnut locks down loose and highlighted her naturally elegant features with a pop of rosy blusher.

For the special occasion, Princess Kate and her mini-me daughter Princess Charlotte twinned in white. Kate's outfit was made in an ivory silk crepe material, with silver bullion and threadwork embroidery featuring rose, thistle, daffodil and shamrock motifs – to signify the four nations of the UK.

Like mother, like daughter, Princess Charlotte similarly donned a custom Alexander McQueen dress. And in a show of unity, both royal ladies completed their looks with matching bespoke headpieces made in a collaboration between milliner Jess Collett and Alexander McQueen. Stunning!
