On Saturday, the Duchess of Cambridge attended the women's final at Wimbledon alongside her husband, Prince William, wearing the perfect summer dress. Returning to the stands in style, Kate slipped on a chic green midi dress with cap sleeves, and accessorized with white pumps and a blue floral face mask. And at one point during the match, she put on a pair of Ray Ban sunglasses that seemingly matched Will's set. William, for his part, kept it classic in a linen blue suit and a navy tie. Kate Middleton and Meghan Markle Are "In a Better Place" After Lilibet's Arrival Earlier this week, Kensington Palace announced that Kate would be entering a period of quarantine after coming into contact with someone who tested positive for COVID-19. "Her Royal Highness is not experiencing any symptoms, but is following all relevant government guidelines and is self-isolating at home," the palace's statement revealed. According to People, Kate was reportedly exposed during her initial trip to Wimbledon, where the audience was filled with "several hundred members of frontline staff, patients and others involved in the NHS response to COVID-19." For that engagement, the duchess made the case for preppy polka dots in a blue and white pleated skirt, which she paired with a simple white T-shirt underneath a fitted navy blazer.
