On Saturday, the Duke and Duchess of Cambridge attended the women's final at Wimbledon.
Kate Middleton wore a bright-green, cap-sleeved dress and sunglasses as she sat next to a suit-clad Prince William. The duchess is a frequent attendee at Wimbledon and is known for making fashion statements at the annual tennis tournament in London.
Middleton took to the court on Saturday to award Wimbledon women's singles champion, Ashleigh Barty of Australia, with the gold Venus Rosewater Dish trophy after she defeated the Czech Republic's Karolina Pliskova.
Middleton's appearance at Wimbledon marked her first public outing since Kensington Palace announced that she entered self-isolation after coming into contact with someone who tested positive for COVID-19.
"Last week The Duchess of Cambridge came into contact with someone who has subsequently tested positive for COVID-19," a palace spokesperson previously told Insider in a statement. "Her Royal Highness is not experiencing any symptoms, but is following all relevant government guidelines and is self-isolating at home."
In May, Middleton received her first dose of the COVID-19 vaccine at London's science museum.
Before isolation, Middleton attended the Wimbledon tournament on July 2, and the week prior, she went to a Euro 2020 match with Prince William and their oldest son, Prince George.
A source close to Kensington Palace told Insider that Middleton takes lateral flow tests twice weekly as part of the royal household's COVID-19 testing procedures. The same source told Insider that both of Middleton's tests before the Euro match and Wimbledon were negative and that the duchess "followed the rules throughout Wimbledon about when to wear a mask."
Prince William also received his COVID-19 vaccine in May, a week before Middleton got hers.
