An expert is sharing an insight into the almost fashion faux-pas Kate Middleton reportedly had at a royal event in 2018.

Speaking to Express UK, jewellerybox PR, Social and Digital Marketing Manager Daena Borrowman recalled the moment in question and looked into what the working royal could have done to prevent any further similar wardrobe mishaps.

The expert recollected in the exchange that the Princess of Wales wore an Alexander McQueen pink dress to the wedding of Princess Eugenie and Jack Brooksbank in 2018. She said the “wind began to catch Kate’s dress” at one point in the event, but “calmly smiled at the moment” with Sophie, Countess of Wessex’s help.

Citing royal insiders for the claim, Borrowman told the outlet that “it is common for royal women to have small weights sewn into the hems of their skirts and coats to avoid wardrobe malfunctions and allow them to fit perfectly.”

The expert continued in the engagement that the late Queen is said to have “passed down her tricks” in fashion to Kate Middleton, adding, “as she too would have circular lead curtain weights sewn into all of her handmade outfits.”

Borrowman later said, “Pennies or small weights are sewn into the hemlines of dresses to avoid them being blown up” by a strong wind, as per the outlet.

The expert also told the publication that the stylists of the Princess of Wales “would have been aware of the protocols to follow to avoid any embarrassing situations.” She subsequently noted that royal stylists and dressers have to follow “dozens of protocols in place” for the prevention of fashion faux pas and mishaps.

Princess Eugenie tied the knot with Jack Brooksbank earlier in October 2018.

At the time, Closer Weekly reported that the wind was 21 mph in Windsor, England, adding that the gusts of wind outside St. George’s Chapel nearly blew the stunning piece Kate Middleton wore that day for the royal event.

It noted, though, that the hem of the dress stopped just above the royal’s knee, adding that she seemed to laugh it off, while Sophie, Countess of Wessex, appeared to have had an eye out for her niece-in-law.

Elsewhere in the exchange with Express UK, published Sunday, Daena Borrowman shared that members of the British Royal Family, especially senior working royals, customarily “dress modestly during public appearances to preserve the sanctity” of the family.

Aside from noting that female royals “wear tights when their legs are exposed in public,” the expert also pointed out that they are “discouraged,” as well, “from showing off their cleavage,” adding that there are several other style and fashion protocols they, including the Princess of Wales, should follow.
