Princess Elisabeth proved she's part of the next wave of royal fashionistas on Monday as she stepped out alongside her parents, Queen Mathilde and King Philippe, and siblings Princess Eleonore, Prince Gabriel, and Prince Emmanuel to attend Belgian National Day celebrations in the Parc du Cinquantenaire in Brussels.
The heir to the Belgian throne, 23, was seen wearing a stunning Victoria Beckham gown with a one-shoulder design. The floral number also featured a ruched bodice and an asymmetrical skirt with a satin underlayer.
For her accessories, Elisabeth added a pair of patent stiletto pumps, as well as a clutch from her mother's collection – the 'Zoey' style by Olga Berg.
For her beauty look, the princess rocked a shimmering blue eyeshadow moment and a rosy-hued lip. Her sister, Princess Eleanore, 17, matched her stylish energy in a white broderie anglaise dress while her mother, Queen Mathilde, 52, opted for a bird printed dress by Dries van Noten and a pair of killer red Natan heels.
Oriona Robb, celebrity fashion stylist, tells HELLO! that Princess Elisabeth's look is a masterclass in modern royal elegance.
"The soft blue patterned dress strikes a perfect balance between youthful charm and poised sophistication," she says. "Its gentle silhouette and subtle cinching at the waist enhance her natural grace without feeling over-styled."
Meanwhile, stylist Angela Kyte adds: "It's elegant without trying too hard, and that's exactly where her style power lies."
The designer number featured a sheer top with a high neck, which met a full ankle-length skirt. The look was accessorised with the 'Metropolitan Insignia Clutch in Gold' by Carolina Herrera, which her mother carried during the state visit to the Czech Republic in June, and topped it off with her mother's gold Herve Van Der Straeten earrings to match her Atelier Anne Stoffels headband.
For the party in Brussels Park, the royal, who has recently completed the first year of her two-year master's degree in public policy at Harvard University, opted for a sleeveless printed denim dress by Erdem with strappy 'Portofino 105' heels by Gianvito Rossi and a pair of Giorgio Armani earrings.
