Kate’s topless photo scandal: September 2012

During Kate and William’s romantic rendezvous in Provence, France, tabloid photographers snapped a topless Kate sunbathing at the private chateau they were staying at at the time.

Eventually, the salacious photos made their way into Closer magazine and local newspaper La Provence, leading to swift backlash from the royals.

“The incident is reminiscent of the worst excesses of the press and paparazzi during the life of Diana, Princess of Wales, and all the more upsetting to The Duke and Duchess for being so,” a spokesman for St. James's Palace stated. “Their Royal Highnesses had every expectation of privacy in the remote house. It is unthinkable that anyone should take such photographs, let alone publish them.”

Closer magazine was ultimately ordered to pay nearly $120,000 in damages.

Kate’s BAFTA Awards dress controversy: February 2018

At the height of the Time’s Up movement, most women wore black dresses to the 2018 BAFTA Awards to show their support. Middleton, however, opted for a dark green outfit complete with a black sash.

Royals are prohibited from voting and speaking publicly about politics, so it’s no surprise Kate avoided the black dress.

The uproar, however, came afterward, when Kate showed up to co-host the Commonwealth Fashion Exchange reception in a black-and-white dress — leading to an instant social media backlash.
