Now seven months pregnant, the Duchess of Cambridge might have expected all eyes to be on her sizeable bump.
But windy weather and her flimsy outfit had other ideas. Kate was left red-faced after the gusts lifted up her £38 polka-dot dress, drawing attention instead to her thighs.
The royal mother-to-be was caught out by the wind as she arrived at the wedding of friends Willian van Cutsem and Rosie Ruck Keene, in south Oxfordshire, just over a week ago.
Whoops: A seven months pregnant Duchess of Cambridge was hit by an unfortunate gust of wind which blew up her skirt and exposed her thighs
Seemingly unaware that her skirt had blown up, revealing her shapely legs, she gripped her black and white fascinator rather than her hem, laughing as she did so.
It happened as she walked towards St Mary the Virgin Church, in the village of Ewelme in the Chiltern Hills, on Saturday, May 11.
The duchess appeared not to have learned her lesson from the last time she wore the Topshop dress, when she suffered a similar wardrobe malfunction.

She was forced to hold down the back of the black and cream outfit as she arrived at the Hertfordshire-based Warner Bros Studios with Princes William and Harry, last month.
The High Street bargain sold out within hours of her wearing it, but the dress may not get a third showing after proving unsuitable for the gusty British weather once again.
Kate attended the wedding with Prince William, who arrived separately and was believed to have been an usher, wearing the same morning suit, blue striped shirt, and dark red tie as the groom.

The couple have known the van Cutsem family for many years and the groom’s niece, Grace, was a flower girl at the royal wedding.
Kate’s embarrassing moment, reminiscent of Marilyn Monroe in film The Seven Year Itch, was one of several for the duchess.
In July 2011, during a North American tour, her cream and navy cable-knit Alexander McQueen dress was whipped up by the wind as she met wellwishers in Charlottetown, in Canada.
On that occasion she was wearing a cream slip, which protected her modesty. She was not so lucky four days later as her yellow Jenny Packham dress flew up on the tarmac at Calgary airport, briefly revealing her underwear.
But the duchess, who is expected to give birth on July 13, handled all the mishaps with her usual poise.
The exact due date had been shrouded in secrecy, but close friends of the royal couple discussed at a barbecue hosted by a family friend that Kate expects to go into labour on July 13 – during the Queen’s Coronation Festival.
For the first time, 50 per cent said Charles would be a fitting monarch in the YouGov poll, up 13 per cent from May last year. The Prince of Wales was seen as making a positive contribution to the monarchy by 60 per cent of voters.
The poll showed, for the first time, a majority believe the Queen should abdicate if she becomes too ill to fulfil her duties.

On Saturday, Pippa Middleton made an obligatory appearance at a scoiety wedding.
But the happy couple’s choice of toast was more suited to The Only Way is Essex than its higher-class Chelsea counterpart.
Guests toasted the bride and groom with Smirnoff Ice, a vodka alcopop flavoured with lemon, and knocked back gin shots before the service, according to onlookers.
The Duchess of Cambridge’s little sister attended the wedding of Verity Evetts and Christopher Buchanan at the Church of St Peter and Holy Cross, Wherwell, Hampshire.
Showing off her famous figure in a skin-tight pale pink £370 Tory Burch Adelaide dress, she looked stylish and svelte as she posed for the cameras.
