The Duchess of Cambridge is wearing a blue dress by Seraphine - a brand she's worn a lot during her pregnancy.
The Duchess of Cambridge officially opens the new Place2Be Headquarters.
Duchess Kate recently wore the same dress during her royal tour to Norway.
She's the future Queen but she's always been the queen of recycling her clothes like the rest of us!
Kate is seen here visiting with children from the Place2Be Headquarters.
Clearly, she's having a great time!
