The Queen of thrifty fashion! Mary of Denmark dons outfit she first ...

Queen Mary of Denmark opted for a stunning sequin skirt and off-the-shoulder top first worn 17 years ago

Queen Mary of Denmark dazzled at a State Council Dinner this week - donning a sequin ensemble she first wore back in 2007.

The wife of the Danish monarch, 52, opted for a sequin skirt and black satin off-the-shoulder blouse as she attended the event at her home of Frederik VIII's Palace alongside King Frederik.

The thrifty Australian was first seen wearing the outfit during a visit to New York in 2007 when she paired the look with a dark clutch and drop diamond earrings. During this week's event, she swept her hair into a sleek low bun for the occasion, with two tendrils framing her face. The mother-of-two opted for a soft smokey eye and a touch of bronzer for the big event.

Meanwhile King Frederik was smart as he donned a stylish blue tuxedo for the outing.

King Frederik and Queen Mary were pictured greeting guests ahead of the State Council Dinner before posing for photographs on the steps of their home.

The appearance from the couple comes after Casanova made tentative steps back into the spotlight, following tabloid speculation abound of a possible affair with King Frederik.

Casanova, a model, charity activist and former reality TV star, was pictured on a late night out in Madrid at the end of last year, thrusting the rumour mill into overdrive. The images were explained at the time by HOLA! in the following terms: Frederik and a mutual friend of his and Genoveva’s had plans to attend an exhibition together. After the friend pulled out, Genoveva was asked to go in his place. The pair then walked through the park and had a public dinner together at ‘El Corral de la Morería’.

After the debacle surrounding the pictures, which were published in Spanish magazine Lecturas, Casanova disappeared from social media. Weeks later, Frederik’s mother Queen Margrethe II shockingly abdicated and he ascended the Danish throne amid scenes of jubilation in Copenhagen.

Yet the rumours show no sign of slowing down - it also emerged in recent weeks that King Frederik returned to Spain for a private trip earlier this year. It is not clear exactly when Frederik returned to Spain but it has been suggested in HOLA! that the King was last in Madrid just three weeks ago, perhaps making his first visit since the coronation.
