Meghan Markle cheered Princes Harry and William on as they played in the Audi Polo Challenge in Berkshire this weekend. The charity event was put on by Audi in support of charities including Tusk, which protects wildlife throughout Africa.
Meghan tackled heatwave dressing in a sleeveless belted gingham eyelet dress in the colour 'Sand,' designed by Shoshanna Ashland, which is now – you guessed it – sold out, but cost around £299 and was sold through Neiman Marcus.
The sandals she wore, however, are still available in some limited sizes. They’re a £186 pair of handcrafted Sarah Flint sandals – a brand Meghan has worn many times before, including at the Invictus Games with Harry, and at an Anzac Day service at Westminster Abbey. Meghan topped it all off with a £52 Madewell x Biltmore Panama hat.
She was joined by friend and tennis champion Serena Williams, who was one of Meghan’s wedding guests. Serena was apparently so keen to accompany her friend Meghan that she cancelled a pre-Wimbledon press conference she was scheduled to give.

Serena’s husband, Reddit founder Alexis Ohanian, was also in attendance at the charity match where Harry’s team won 5-2.
