Kate Middleton made a subtle but stylish nod to female empowerment this week, as she attended a royal engagement with a particularly poignant piece of jewellery. The Princess of Wales wowed staff and patients on Wednesday when she visited Royal Surrey County Hospital’s maternity unit, dressed in a mustard yellow dress, to hear more about the the holistic support it provides to pregnant women and new mothers to ensure they receive the best possible care throughout and beyond their pregnancies.
