The royals have been attending Wimbledon for years, and since many of them are big fans of the sport, the Championships are a big highlight in their calendar.
The grass tennis tournament in SW19 is also a fantastic opportunity to see the best of royal fashion and beauty looks.
While fans are used to seeing the likes of the Prince and Princess of Wales and Zara and Mike Tindall sitting in the royal box, Princess Anne is one royal who hasn't been seen at the championships in recent years.
However, she did make an appearance at SW19 back in 1967, and she looked totally different!

In an unearthed photo from the archives, King Charles' sister was seen sporting a sleek bob hairstyle when she attended the AELTC in 1967.

Avid royal followers will know that her interests lie with equestrian sports. The former Olympian can usually be found attending showjumping tournaments and, of course, Royal Ascot. She is also a keen rugby fan, having been a patron of the Scottish Rugby Union since 1986.
Royal tennis fans include the Princess of Wales, the Duke of Edinburgh, Prince Michael of Kent and the Duchess of Gloucester.

The Princess Royal's outfit was perfectly in keeping with the swinging sixties fashion at the time, and allowed the hat to do all of the fashion talking.

While the Princess Royal has kept to her signature updo over the past 40 years, she was astonished to discover that the hair and makeup department on The Crown used to take two hours to recreate it.
In Anne: The Princess Royal at 70 documentary, released in 2020, the late Queen's only daughter said: "Actually, I read an article the other day about the – I don't watch Netflix and The Crown... but the actress was talking about how long it took them to do their hair like I did.
"And I'm thinking, 'How could you possibly take that long?' I mean, it takes me 10 or 15 minutes."
