Kate Middleton radiant in powder blue Emilia Wickstead ahead of Wimbledon men's final
Katherine Jenkins, Benedict Cumberbatch, and Tom Hiddleston were also invited to the royal box
The Duke and Duchess of Cambridge have arrived at Wimbledon for Roger Federer's clash with Novak Djokovic.
Kate is wearing a pale blue mid-length dress with nude heels, while William looks casual in a grey suit jacket with navy trousers.
The royal couple met with senior figures from the All England Lawn Tennis Club, including head referee and former player Andrew Jarrett.
They also met with four of the club's team of ball boys and girls.
Kate's powder blue 50s-style dress is from a collection by London-based designer Emilia Wickstead.
Among the famous names to receive an invite to the royal box are Sherlock star Benedict Cumberbatch, The Avengers' Tom Hiddleston and Fight Club star Edward Norton.
Multi-billionaire Amazon founder Jeff Bezos also received a coveted invite to the royal box.
He was accompanied by his new girlfriend Lauren Sanchez following his split from his wife of 26 years MacKenzie Bezos.
Opera singer Katherine Jenkins and her husband Andrew Levitas also arrived at Wimbledon ahead of play on Saturday morning.
"This is our favourite day out in probably all the London summer events," Ms Jenkins said.
The Welsh singer sang at the opening of Centre Court's retractable roof in 2009 and said it had "a great acoustic".
"Always my family has been into tennis and I think my mum was very proud when I got to sing here," she said.
A host of former tennis greats are also in prime seats in the royal box, including former world number one Rod Laver and 18-time grand slam winner Chrissie Evert.
It is Kate's third visit to the championships this year.
On Saturday she sat alongside her sister-in-law the Duchess of Sussex to watch Serena Williams crash to a straight sets defeat against Simona Halep in the women's final.
Halep, who previously shared her hopes of seeing Kate in the royal box, said it was an "honour" and "an extra boost" to play in front of the duchesses.
Kate was among the first people to congratulate the Romanian as she left the court to celebrate her maiden Wimbledon title.
Earlier in the tournament, Kate enjoyed a behind-the-scenes tour of the club and made the rare move of watching a game on one of its outside courts.
Her visits have included meeting British players past and present, junior competitors and the project managers behind the recently redeveloped Number One Court.
The Duke and Duchess of Cambridge's meeting with senior figures at Wimbledon today was momentarily interrupted when Roger Federer crossed the bridge between the Millennium building and Centre Court.
Federer was greeted by loud cheers from fans waiting on the path below.
