Stepping out for a political summit in the Danish capital on January 31, the Australian-born royal rocked a pair of beautifully tailored wide leg pants with a neat black turtle neck.
The Crown Princess covered up against the Scandinavian chill with a black, knee length button coat and charcoal grey boot heels.
She accessorised the look with a matching grey clutch and flower shaped stud earrings, perfectly complimented by her trademark bouncy blow dry and immaculate makeup.
Ramping up the glamour for an appearance at Copenhagen Fashion Week the next day, the mother-of-four was the epitome of winter elegance in a flowing, pleated skirt and a quirky grey tweed blazer.
To add finesse, the 46-year-old fixed a dainty butterfly brooch to the jacket.
Her hair was styled straight and sleek whilst her crimson nails created a welcome pop of colour against the monochrome outfit.
Princess Mary, who is known for her philanthropy and involvement in community initiatives, attended the sartorial event to present the Women's Board Award 2019.
Copenhagen Fashion Week is the largest fashion event in the Nordic region, attracting a bevvy of celebrities, models and social media influencers every year.
