Prince Harry and big brother William were playing at the Audi Polo Cup on Saturday, the day before their late mother Princess Diana’s birthday.
Meghan was joined by her old friend Serena Williams, and Serena’s husband Alex Ohanian.
The Duchess was flanked by security and seems eager to avoid the cameras, but was full of smiles in the summer sun.
With the temperature at Cowarth Park Polo Club in Berkshire nearing 30C, Meghan wore an appropriately cool summer dress.
The Duchess of Sussex looked effortlessly chic in a cotton gingham Ashland shirt dress.
The dress was designed by Shoshanna Gruss and cost £299 - and is already sold out.
Meghan paired the summery dress with a pair of brown strappy flat sandals from Sarah Flint NY.
Finishing the look off, the stylish Duchess wore a pair of sunglasses and a white-and-black Madewell x Biltmore Panama hat, which is also sold out.
