She may have been just one of hundreds of guests at her grandparents' diamond wedding celebration but Zara Phillips certainly stood out from the crowd in an attention grabbing - and leg flashing - outfit.
While other young royals turned out in more sedate attire as they descended on Westminster Abbey for the lavish service, Princess Anne's horse-riding daughter settled for something a little more racy.
She teamed a thigh-grazing skirt with opaque black tights, double-breasted grey coat with contrasting cuffs and collar - and sky scraper lace-up heels.
To complete her super-chic outfit, Zara, 26, ditched the usual elaborate floral headpiece for a streamlined black beret.
Nor was the young royal the only one to show off her fashion credentials.

Sixty years ago the bride wore white - and yesterday, once again, the Queen arrived in a white outfit to celebrate her diamond anniversary.
In a ceremony that bore remarkable echoes of their wedding service, she and the Duke of Edinburgh walked down the same aisle at Westminster Abbey where, 60 years ago tomorrow, they became man and wife.
Then, in a service that was seen as a welcome splash of colour amid the austerity of post-war Britain, she wore an ivory silk Norman Hartnell gown, decorated with 10,000 seed pearls, glittering crystals and featuring an intricate 13ft star-patterned train. Today, a lifetime on, the 81-year-old Queen wore a matching ivory coat and hat.
She is the first monarch in British history to celebrate 60 years of marriage, a union praised by the Archbishop of Canterbury today in his address as a faithful and creative partnership lived in the "full light of publicity".
Dr Rowan Williams said the milestone was a symbol of the relationship between the people and monarch and was part of her "unqualified commitment" to every aspect of her reign.

That dedication and dignity was reflected today throughout the service, and broken only after the blessing by the Archbishop when she permitted herself a brief smile in response to a remark by the Duke.
The royal couple were surrounded by their family, senior politicians past and present, and a 2,000-strong congregation including about 20 couples who were married on the same day.
As an indication of how much life has passed since, one of the readings was given by the Queen's grandson, Prince William, who at 25 is four years older than the then Princess Elizabeth was when she married.
They were different times then: the Second World War had only been over for two years, and rationing was still in place.
When the original kneelers were being restored for use by the couple at today's service, it was discovered that they had been made from wartime orange boxes, covered with damask rose silk - as fitting a symbol as any of how the wedding was seen as a much-needed morale boost in those days of dour frugality.
There were several reminders of the original service, from the introit, "We wait for thy loving kindness, O God", which was composed for the ceremony by the Abbey's then organist Dr William McKie, to the musical setting for Psalm 23, Crimond, then a little known Scottish air, requested especially for her wedding by Princess Elizabeth.

The congregation included the Prince of Wales, the Duchess of Cornwall - seated directly behind the Queen - and Princes William and Harry, military chiefs of staff and some of the Queen's godchildren.
Some of the royal family there had played a part in the wedding: Princess Alexandra, then 10, was the youngest bridesmaid, and Prince Michael of Kent, then five, was a page boy.
Dame Judi Dench read a specially commissioned poem by poet laureate Andrew Motion, Diamond Wedding, which spoke of "a life remote from ours because it asked each day, each action to be kept in view".
In his address, the Archbishop spoke of how the Queen and Duke have had to live their lives "more than others in the full light of publicity".
He said: "We are probably more aware than ever these days of the pressures this brings. But it also means that we can give special thanks for the very public character of the witness and the sign offered to us by this marriage, and what it has meant to nation and Commonwealth over the decades.
"And part of what it has meant has had to do precisely with the sense of unqualified commitment that has been so characteristic of every aspect of this reign: the faithful and creative personal partnership at the centre of everything else has been a sign of creative faithfulness to a task, a vocation, the creative faithfulness that secures the trust, love and prayerful support of millions."

Today the Queen and Duke fly to Malta, where he was on naval service in their early marriage and they had their only real taste of life as a relatively ordinary couple.
On Sunday, the Queen and Prince Phillip's eldest son, the Prince of Wales, threw a dinner party for the couple.
From the newest addition to the Windsor clan - Autumn Kelly, the Canadian fiancee of their grandson Peter Phillips - to the Duke and Duchess of Gloucester, every generation of the Windsor dynasty was represented.
As family gatherings go, it was one to strike fear into the heart of even the most socially accomplished young woman. But by all accounts, Miss Kelly breezed through her first official engagement as a member of the Royal Family.
The dinner to mark the monarch's diamond wedding anniversary wasn't the first time she had met her fiancees grandparents - she was invited into the Royal Box at Ascot this year.
But she has never taken part in such a formal event before and was included in the official pictures afterwards. Royal sources said her presence is a sign of acceptance by the Queen, who dotes on her eldest grandson.

Generations unite: The royals gather round the Queen and the Duke of Edinburgh to mark the couple's diamond wedding anniversary with a dinner at Clarence House last night
The lavish banquet, thrown by Prince Charles at Clarence House, his London residence, was billed as an intimate, private family occasion, a chance for the Queen and the Duke of Edinburgh to quietly toast the success of their union with the dynasty that it has created.
Buckingham Palace has also released a photograph showing the 81-year-old Queen and her husband, 87, recreating their official honeymoon portrait.
The original black and white picture was taken in the grounds at Broadlands, the family home of Earl Mountbatten, Philip's uncle, in Hampshire following their wedding on November 20, 1947.
In addition to the Queen and the Duke, 23 members of the Royal Family were present. Among them were Viscount Linley and Lady Sarah Chatto, the children of the Queens late sister, Princess Margaret, as well as six of her seven grand-children.
Only four-year-old Lady Louise Wessex was missing because she was too young to attend, but her heavily-pregnant mother, the Countess of Wessex, who is expecting her second baby in a few weeks, looked radiant.
While the men looked uniformly smart in dinner jackets, there was a smattering of colour among the ladies… Princess Beatrice, 19, in daringly low-cut chocolate brown and her sister, Eugenie, 17, in brilliant blue.
Princess Anne looked enviably trim in oyster brocade while the Duchess of Cornwall wore a dark green velvet couture dress with her family diamonds. Zara played it uncharacteristically safe, however, in a black jacket clinched in at the waist with a trendy wide belt.
The only commoner there was Miss Kelly. She is a management consultant and her clients include Michael Parkinson. She met Peter at the Canadian Grand Prix in Montreal four years ago.
They split their time between Anne's Gatcombe Park estate in Gloucestershire, where they have a cottage, and a home in Edinburgh where Peter, 30, works in the Royal Bank of Scotland's sponsorship department.
They are expected to tie the knot in St George's Chapel at Windsor Castle in May.
