Kate swaps red Preen cocktail dress for black at charity gala

The Duchess of Cambridge, née Kate Middleton, loved the red Preen cocktail dress she wore while on tour in Canada so much, she also bought it in black. The mother of two stepped out in a noir version of the Finella dress to attend this year's Place2Be Wellbeing in School Awards at Mansion House in London.

Kate paired the elegant midi dress with a Temperley London crystal bow belt and suede cutout wave pumps by Prada. It was a quick change for the 34-year-old, who earlier in the day visited the Natural History Museum in a floral L.K. Bennett creation.

As patron of Place2Be, Kate took to the podium to congratulate award winners. "Tonight, we are celebrating the truly remarkable work taking place across Place2Be schools in support of children’s mental health," said the duchess, adding, "Without many of the inspiring people gathered here, countless children would not receive such transformational support in their schools. It is because of so many of you, that in their time of need, children have the help that will get them through tough times in their lives."

The mother of two congratulated the night's winners during a moving speech.

The royal went on to reflect on her time as patron of the charity, saying "'I have been privileged over recent years to visit schools & meet the teachers, volunteers, and parents who make Place2Be work a reality. Together, you ensure all of your students know they have somewhere to turn, someone who will listen, or simply a safe place to escape."

Kate wore the red version of the Finella dress in Canada.

Earlier this year, Kate made a dazzling appearance at Government House in Victoria wearing the red version of the Finella dress. For that occasion, she accessorized with the Queen’s diamond maple leaf brooch, her red suede Miu Miu clutch and matching stilettos. Her hair was tied in a low chignon, letting the dress take centre stage.
