Sarah Ferguson just gave a major nod to the royal family in the most touching way.

While in Canada, the Duchess of York attended the T.M. Glass Solo exhibition titled “The Audible Language of Flowers.” Ferguson opted to wear a stylish green dress, which was cut just above her knees. She accentuated her dress with her gold hoop earrings.

Ferguson also wore a pair of black shoes, which are believed to be a limited-edition pair by Del Toro x Rotted Road Never Complain Slipper. Ferguson’s footwear literally had the words “Never Complain, Never Explain” written on them.

Jess Sheldon, a journalist for Express, said that while the statement may not mean anything, it could also be closely linked to the British royal family. The phrase was reportedly coined by the British political and former Prime Minister Benjamin Disraeli, who lived between 1804 and 1881.

The members of the royal family are also known to follow the unwritten rule of never complain and never explain. Royal biographer Duncan Larcombe commented on this supposed royal tradition in the book “Prince Harry: The Inside Story.”

“There is an old rule of royal when it comes to their interaction with the media – ‘never complain, never explain.’ To be seen to break either of these unwritten rules is generally considered to be a no-no, risking being dragged into a wider row that could ultimately backfire,” he said.

But Ferguson’s recent sighting was not the first time that she sported her unique pair of shoes. The mom of two previously wore them at a Street Child UK Education in Emergencies event in February, which she attended with her eldest daughter Princess Beatrice.

In related news, Ferguson also made headlines this week after it was revealed that Prince Philip never really forgave her for the controversial toe-sucking photos that she starred in shortly after her divorce from Prince Andrew.

The couple has been separated since 1992 and divorced since 1996.
