Crown Princess Mette-Marit of Norway stepped out for a public appearance with her husband Crown Prince Haakon. The sighting alongside her 18-year-old son Prince Sverre Magnus wasn't the only rare part of the outing, however.
The Norwegian royal, 50, was spotted at the annual Friendship Football match at Skaugum where she looked unusually casual in an unexpected double denim ensemble.
more royal style
Rarely-seen jeans
The Crown Princess wore a pair of mid-wash blue skinny jeans with a light-wash denim shirt which featured a collared neckline and utility pockets across the chest.
Unroyal accessories
Dressing her look down further, the future queen styled the laid-back combo with a bright red raincoat and a pair of ankle-skimming Wellington boots.
Hair and makeup
Adding a touch of royal elegance to her look was Mette-Marit's hair and makeup looks. Her icy blonde locks were styled in voluminous waves which cascaded over her shoulders and her makeup was kept simple with a radiant complexion and defined eyebrows.
Rounding off the look were her chic Saint Laurent tortoiseshell sunglasses.
Casual attire
The royal has proven she is not afraid of breaking royal fashion rules and opting for a more relaxed look. She was seen earlier this month in jeans and running shoes as she walked around the Ulsrudvann lake in Ostmarka during the official state visit of King Frederik and Queen Mary of Denmark.
A royal reunion
The royal foursome was later seen flying under the radar on the Norwegian tube.
A style switch-up
The royal was seen rocking an opposing look to the Opening of the Culture Days at Blakstad Hospital in Vettre on 28 May.
The mother-of-three was seen wearing a tasteful linen shirt dress, the 'Frida' from Max Mara, which featured a tied-in waist, button-down-front, and rolled sleeves.
Summer accessories
The floaty summer-ready number was teamed with a pair of baby pink suede heels to match her 'Entrelace' clutch from Maria La Rosa and her 'Triomphe S167' sunglasses from Celine.
Balcony waves
Mette-Marit's daughter Princess Ingrid wasn't present at the football event on Wednesday but was seen with her mother earlier this month in military uniform from the balcony of the Royal Palace in Oslo, on Norway's National Day.
