It's happened again - Kate has had another Marilyn Moment, this time during her tour of India
And of course it has happened to Kate several times before. Her last big royal tour, to Australia and New Zealand, featured a duchess juggling a baby and trying to keep her red skirt in check as she left the plane on arrival in Wellington.
There was another just a few days later during the trip to Australia but the most famous is perhaps the one that happened on an airfield in Calgary during her tour of Canada in 2011 when a primrose yellow dress battled in vain against the strong currents swirling around the place.
It was nowhere near the issue it had been several years earlier when she chose a pleated white chiffon skirt for an engagement and found it making an escape towards her blue jacket. She fought it back into place but not before there had been a photo she'd rather not have had taken. Even Queen Maxima has been caught out - she had to quickly battle an errant hemline while in Normandy for an event commemorating the 70th anniversary of the D-Day landings in 2014.
And at Princess Charlotte's christening, the Duchess of Cornwall found the light Norfolk breezes of July aren't really compatible with chiffon on her way out of the service.
It might be that modern royal dressing doesn't suit weights but then modern royal life needs them - when royals are on show more than ever before and catching an image takes a matter of moments then even the lightest gust mixed with the lightest skirt can cause problems. Kate will be hoping the rest of her dresses stay put as Royal Tour India continues otherwise she risks making Marilyn Moments all her very own.
