See Prince George and Princess Charlotte (in Adorable Sunglasses!) at Their Most Candid Yet
The royal dad was playing to benefit the Royal Marsden cancer hospital and Centrepoint, a homeless youth charity — two organizations he regularly supports.
Charlotte had an adorable fashion moment of her own, rocking little pink sunglasses to match her sundress.
Longtime polo fan William kept things going on the field, while his kids stole the show on the sidelines.
George and Charlotte charmingly ran around the field.
Kate, wearing a pair of neutral espadrilles, saw some action, too, and sprang to her feet at the end of the match.
The mother of three raced towards William to congratulate his team after the game.
