Kate Middleton has had a lot of Marilyn Monroe moments over the years.

The Duchess of Cambridge wears dresses most of the time when she attends royal engagements. This makes Middleton prone to having her skirt blown up, like Monroe’s iconic flying skirt. Here are some of Middleton’s Marilyn Monroe moments that the duchess might not forget.

Canadian Tour in 2011

In 2011, just months after tying the knot with Prince William, Middleton joined her husband for an official visit to Canada. During the couple’s arrival at Calgary Airport, a gust of wind blew the duchess’ yellow dress and exposed her thighs.

Australia tour in 2012

Middleton had the most serious wardrobe malfunction in 2012 during her Australian tour with Prince William. Middleton accidentally flashed her derrière for the whole world to see when a heavy wind blew her dress up. Although the incident was very embarrassing, many praised Middleton’s “great bum.”

London in 2013

In 2013, Middleton suffered a wardrobe malfunction and barely escaped flashing her undergarment to the photographers during a charity engagement at the Clifford Chance building in Canary Wharf. Middleton was wearing an Orla Kiely skirt when a gust of wind blew as she bent down to accept flowers from 9-year-old school girl Tierney Potter. According to Us Weekly, Middleton remained poised after the incident. Meanwhile, Potter admitted that she was “nervous but excited.”

Australia and Canada tour in 2014

The Duke and Duchess of Cambridge went on a royal tour of Australia and Canada in 2014 with their firstborn, Prince George. Upon arrival, Prince William and Middleton were photographed descending the airstair together with the duchess carrying their son. Middleton accidentally flashed her legs when her skirt flew.

Princess Eugenie’s royal wedding in 2018

Last October, Middleton joined Prince William, Meghan Markle, Prince Harry and the rest of the members of the royal family to celebrate Princess Eugenie and Jack Brooksbank’s royal wedding. As the royals stood outside the church, Middleton was photographed having another Marilyn Monroe moment as she accidentally flashed her thighs. Middleton kept her poise and remained smiling while trying to hold her skirt down.

The royals have a secret to avoiding Marilyn Monroe moments. Middleton and Markle usually wear body suits and clothes that increases static so it’s harder for something to fly up. Meanwhile, Queen Elizabeth II added weights into the hemline of her dresses and coats to make it hang beautifully.
