Sophie arrived at the annual horse race event with the Duke of Edinburgh sharing the second carriage in the royal procession with Lord Soames of Fletching and Lady Sarah Keswick.
For the Berkshire races, Sophie chose a wonderful white belted dress which she paired with a pastel pink hat.
The Suzannah London silk gown, featuring a bow detail and buttons down the front, currently retails for £3,450.
Sophie styled her hair in an elegant updo and sported a pair of pearl and diamond drop earrings for an added touch of glamour.
Lord Soames of Fletching is the grandson of Churchill and early equerry to His Majesty, and Lady Sarah Keswick is the daughter of the late Earl of Dalhousie.
