The Princess Royal has been sporting her signature beehive for over four decades now, but did you know she would frequently have long locks she would wear down in her younger years?
In an unearthed photo from the archives, King Charles' sister was seen sporting a sleek bob hairstyle when she attended Wimbledon in 1967.
The then 16-year-old donned a button-up collared coat as she watched the men's singles final between John Newcombe and Wilhelm Bungert.
While Anne was seen more regularly at the tennis tournament in her youth and even presented Ann Jones with the trophy in 1969, she hasn't put in an appearance at Wimbledon since the 1980s.
The Princess Royal's interests lie more in equestrian sports, where she had an illustrious career, and she is a keen rugby fan, having been 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.
Princess Anne's hair evolution
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."
The Princess is also renowned for her sustainable sense of style, regularly rewearing outfits and hats she has owned for several decades.
Health update
The Princess Royal's busy schedule has been placed on hold amid her recent accident. Anne suffered a minor head injury and concussion after a horse-related incident on her Gatcombe Park estate last month.
Anne spent several days being treated at Southmead Hospital in Bristol before being discharged on 28 June and returning to her Gloucestershire home.
She had been due to attend a memorial ceremony in Canada marking the centenary of the Newfoundland National War Memorial.
The Canadian Governor General shared a message on her behalf which read: "It is with deep regret that I am unable to be with you today, as you commemorate the brave efforts and sacrifices of the members of the Newfoundland Regiment who went into battle on the first day of the Somme."
It continued: "I have fond memories of joining you in 2016, on the 99th occasion that the people of this Island commemorated the Battle of Beaumont Hamel, and I am deeply saddened that I'm unable to join you again, and I send you my warmest best wishes on this special day of commemoration".
