This is what Kate Middleton wore to the Big Lunch in Windsor with Prince William

The Princess of Wales opted for an understated look in a powder blue linen blazer as she surprised royal fans at a Big Lunch gathering in Windsor today.

Her casual ensemble was a world away from her appearance at the coronation of King Charles and Queen Camilla yesterday, when she turned heads in an ivory silk crepe gown by Alexander McQueen.

Kate, 41, had matched her daughter Charlotte, eight, who wore a lookalike McQueen gown and a gorgeous, botanical Jess Collett x Alexander McQueen headpiece.

Today, she toned down the glamour and was back to her typically chic self.

The mother-of-three opted for a £298 linen blazer by Reiss and black trousers as she greeted well-wishers who had gathered outside Windsor Castle to celebrate the coronation.
