The Duchess of Cambridge was seen for the first time since the birth of her third child with Prince William, 35, less then a month ago.
Prince Louis who was born on April 23 – St George’s Day – was not at the wedding.
Kate Middleton wore a stunning Alexander McQueen cream outfit to the Windsor wedding and was pictured standing on the steps on St George’s Chapel with her daughter Princess Charlotte, three, who was a bridesmaid.
The Duchess of Cambridge kept a close eye on her children who had important roles to play at the wedding and arrived with the bride on her big day.
Her Royal Highness, who teamed her look with a statement hat, has worn the cream coat dress on four occasions before the wedding at the weekend.
She wore the summer outfit for Charlotte’s Christening in 2015 and for the Trooping of the Colour in 2016 celebrating the Queen’s 90th birthday.
Kate was also spotted in the outfit last year at the commemorations to mark the centenary of Passchendaele in Ypres.
The mother-of-three complimented her designer wedding attire with a pair of Kiki McDonough earrings.
