The hottest royal you’ve never heard of’ follows in the footsteps of Princes William and Harry with Sandhurst graduation – as his grandmother makes rare appearance at celebrations

The late Queen’s cousin, Princess Alexandra, made a rare public appearance on Friday afternoon to celebrate her grandson graduating from his Royal Military course.

The daughter of Prince George, Duke of Kent, and Princess Marina of Greece and Denmark, 88, opted for a vibrant ensemble for the occasion, which took place at the Royal Military Academy in Sandhurst, Berkshire.

She came together with family to support Alexander Ogilvy, 28, otherwise known as ‘the hottest royal you never heard of’, who was recently accepted into the Household Cavalry following his graduation.

Alexandra put her best fashion foot forward and donned a colourful paisley blouse and emerald green skirt, which she paired with a baby pink scarf and a wide-brimmed tan hat.

The royal opted for glamorous makeup, donning bright pink blusher and rosy lipstick while styling her grey tresses in an elegant updo.

Princess Alexandra, who is Queen Elizabeth’s cousin, was sitting alongside her son James Ogilvy, 61, her daughter-in-law, Julia Ogilvy, 60, and her granddaughter Flora Vesterberg, 30.

Flora, who is married to Swedish financier Timothy Vesterberg, looked effortlessly stylish in a cobalt blue and white satin caped frock designed by Emilia Wickstead.

She paired this with a blue Aspinal of London clutch bag, which was personalised with her gold initials ‘FV’, and a Jane Taylor hat.

Flora wrote on her Instagram on Sunday evening: ‘On our way to the Royal Military Academy Sandhurst to celebrate my wonderful brother!

‘Congratulations @acogilvy on your graduation – and for your acceptance into the Household Cavalry. Very proud of our British Army Officer! #London.’

Flora, who is an art historian and philanthropist, boasts almost 80,000 followers on Instagram, with many gushing over her stunning ensemble.

One fan wrote: ‘Many congratulations to your brother! I love your look!’ Another penned: ‘Congratulations to your brother. You look so beautiful.’ A third commented: ‘This blue look! Stunning on you!’

The clan gathered for the Sovereign’s Parade, which is a special event marking the end of an Officer Cadet’s time at the Royal Military Academy Sandhurst.

They are then commissioned into the British Army and overseas armies, with the occasion taking place three times a year.

Each cadet graduates the 44-week course and is awarded at the parade, a closed-off event attended by family and friends.

Alexander has followed in the footsteps of Prince William, Prince Harry and Prince Edward, who have all graduated from the military academy.

Flora’s followers took to the comment section to share their thoughts about Flora’s ensemble for the occasion

He looked typically dapper in his military uniform as he proudly held his hat and showed off his medals in snaps with his parents, James and Julia, and his brother-in-law, Timothy. 

It was his sister Flora who initially revealed that he had started his training in a heartfelt post on Instagram last year.

She posted: ‘The @cartier Queen’s Cup. Very proud of my brother @acogilvy beginning at RMA Sandhurst this weekend. We’re full of admiration for you. Forever thoughtful and inspiring. Very good luck xx.’

Alexander is the grandson of the late Queen’s cousin, Princess Alexandra of Kent, making him 54th in line to the throne.

Before deciding to join the military, he was based in New York where he worked for Prove, a technology firm. 

HIs graduation comes as Flora revealed she has been diagnosed with autism at the age of 30 in May. 

The royal, who is 62nd in line to the throne, opened up about the diagnosis in a deeply intimate essay published in British Vogue, calling it ‘unexpectedly empowering’.

She detailed her struggles battling ‘the challenges of neurodiversity’ during her formative years, and said the diagnosis has brought ‘a sense of relief as well as validation’.

An art historian and broadcaster, the royal ancestor mostly steers clear of publicity, but is sometimes spotted joining for events in the society circle calendar, including the Chelsea Flower Show, where she was pictured this year with Lady Amelia Windsor.

Reflecting on her diagnosis during Autism Awareness Month, she hoped to ‘contribute to a shift in statistics’, referencing the figure stating that 80 per cent of autistic women remain undiagnosed by the age of 18.

‘Earlier this year, I was diagnosed with autism. I’ve struggled quietly with the challenges of my neurodiversity since childhood, but am now also able to perceive its strengths,’ she wrote.

She told of having received her diagnosis from Dr Dimitrios Paschos, a consultant psychiatrist and Honorary Research Fellow at King’s College London, ahead of beginning her PhD at The Courtauld Institute of Art.

Undergoing multiple psychiatric evaluations over the course of a week earlier this year, Flora was left feeling both relieved and ‘unsettled’ by the final diagnosis.

The royal, who works closely with heritage brands like Tiffany & Co. and Piaget, said it had also impacted the way she approached her job.

She cited diagnostics for people with autism, notably women, who often ‘camouflage’ by mimicking ‘social norms’, habits she said she can relate to.

Nevertheless, her symptoms don’t prevent her from carrying out her work, explaining that she is able to ‘speak eloquently at engagements’.

Indeed, the diagnosis has helped her discover new ways to prepare to ‘over-stimulating environments’.

She said she hoped her opening up about the diagnosis would help contribute to changing the statistic, and that fewer autistic women would be ‘hiding in plain sight’.

Though not a senior royal, Flora is most definitely part of the elite family circle.

For Trooping the Colour 2023, King Charles invited six members of the extended Royal Family to enjoy the flypast from a second balcony situated in the inner quadrangle of Buckingham Palace.

One of these guests was Flora, who stood alongside her husband, Swedish financier Timothy Vesterberg, and Lady Gabriella Kingston.
