Crown Princess Mary wears one of Kate Middleton's go-to designers, while more European royals stun at Opera House banquet

It was a night at the opera for Queen Sonja and King Harald of Norway’s royal birthday party guests. A number of Europe’s most stylish ladies stepped out on Wednesday for a banquet held at Oslo’s Opera House, which was the third royal-studded event of the monarchs’s joint multi-day celebration to mark their 80th birthdays.

Crown Princess Mary of Denmark took a page out of Kate Middleton’s book donning a design by one of the Duchess of Cambridge’s favorite designers, Erdem. The Danish royal stunned wearing a long-sleeve, full-length gown that featured a "Yuki Garden" print by the London-based designer. Mary wasn’t the only future Queen making a floral statement at the May 10 event. Crown Princess Victoria of Sweden wore a sleeveless black gown by Acne Studios that featured bold flower prints and a modest side slit.

Crown Princess Marie-Chantal of Greece made a colorful splash arriving to the gala wearing a pink tiered gown by Valentino. The Greek royal’s sister-in-law, Princess Tatiana, also stunned for the occasion wearing an ethereal white Celia Kritharioti Haute Couture dress. Like Tatiana, Princess Sofia of Sweden also wore white for the evening. Prince Carl Philip’s wife, who is expecting her second child, dressed her growing baby bump in a tiered crochet dress by Alexis clothing.

Meanwhile, Queen Maxima of The Netherlands, Queen Mathilde of Belgium and Crown Princess Mette-Marit of Norway opted for navy shade gowns. Maxima looked regal recycling a gold off-the-shoulder dress by Claes Iversen — which she previously wore in 2016 — that featured a midnight blue lace overlay at the neckline with similar lace designs on the skirt. While Mathilde and Mette-Marit twinned in navy gowns with sequin embroidery.
