Queen Mary's daughter Isabella raises eyebrows with 'rude' t-shirt detail

Queen Mary's daughter has been spotted wearing a t-shirt with a rude detail on it.

Princess Isabella of Denmark, 18, was spotted at a music festival in Denmark, Smukfest, along with her older brother and heir to the throne, Prince Christian, 19.

Both were spotted dancing and vibing to the music, but royal watchers' eyebrows raised when they caught sight of Isabella's outfit.

The third-in-line for the throne appeared to be wearing a t-shirt with a lyric from Danish band Suspekt emblazoned on it, with the words translated into English as "f----d him yesterday".

One royal commentator, Jarl Cordua, wrote on Facebook, "Isn't that exactly what [the royal family's] job is? To maintain a certain standard? To show some kind of style? Dignity?

"I doubt that everyone thinks that's the case when a royal celebrates promiscuity on a shirt.

"I wouldn't recommend making it a habit. Being royal is an obligation and it's probably time for someone to tell [Isabella] that," he added.

But other royal commentators thought it was right for the teenager to let loose.

Danish TV presenter Jim Lyngvild thought the outfit choice was "the best PR move for the Royal House in many years".

"I LOVE that our royal youngsters also have personality and courage – and don't follow the neat pleated flow," he wrote on Facebook.

"The time of the ladies in the hat is over, Princess Isabella is in."

It's not the first time the royal has skirted tradition. When she celebrated her 18th birthday earlier this year, she did so with a portrait of her holding her phone in her hand, a true symbol of Gen Z royalty.
