You can count on a royal appearance at Wimbledon just like you can count on Princess Charlotte making a face when she sees a camera.

Kate Middleton graced the All England Club with her presence on Tuesday to support Harriet Dart, a 22-year-old British tennis player, before later making her way to Centre Court.

The Duchess of Cambridge donned a gorgeous, custom white dress with black detailing by the brand Suzannah, according to E! News. She paired the dress with an Alexander McQueen belt, a black and purple bow brooch and heels by Gianvito Rossi.
