Sophie also made a statement with her other accessories as she stepped out in the plain colour-block outfit.
The former PR wore a special initial necklace, that is personalised to represent her family.
The chain features three pendants to represent the initials of her husband and children –’E’ for Prince Edward, ‘L’ for her daughter Lady Louise Windsor, and a ‘J’ for her son, James, Viscount Severn.
The personalised jewellery trend is another that has been seen across many of the women in the Royal Family, including Kate Middleton and Meghan Markle who have both previously worn their own initial necklaces.
Sophie also wore her statement earrings from independent designer Lucia Odescalchi, which are worth around £175.
