Charlotte had her hair in plaits paired with a sweet navy and white striped summer dress with a white peter pan collar and sandals.

The royal trio attended the swimming heats at the Sandwell Aquatics Centre in Birmingham where the cheeky Princess was seen rolling her eyes at a remark from Prince William.
The family supported and encouraged freestyle hopeful Luke Turley as he competed for England in the 1,500-metre freestyle.
Along with her eye roll at her father, and other moments of bonding between the Duke, Duchess and Princess.
