Princess Catharina-Amalia's feathered ballgown pinched from grandmother Queen Beatrix's wardrobe

Stepping out for the occasion, the eldest daughter of King Willem-Alexander and Queen Maxima of the Netherlands wore a showstopping ballgown that was first worn by her grandmother, Queen Beatrix, according to royal style blogger @royal.fashion.daily on Instagram.

The magnificent feathered green dress cut just below the knees, and featured a magnificent abstract design across the bodice. Contrasting its striking design, the piece's silhouette is actually very classical in style, with a high crew neckline and long sleeves, where the design continues at the cuff. 

Princess Catharina-Amalia's dress was designed by Theresia Vreugdenhil, who made many dresses for Queen Beatrix, including her inauguration robe from 1980. This specific piece was first worn as a floor-length gown by the then-Princess Beatrix for her state visit to Belgium in 1981, and was reworn in a shorter midi length by her daughter-in-law, Queen Maxima, in 2014. 

As someone who writes about royal style every day, I've seen many royals re-wear their outfits, but Princess Catharina-Amalia's latest look is such a masterclass in honouring family heritage and promoting sustainable fashion, in an otherwise rather modern look.

The rest of the 21-year-old Dutch royal's look was equally brilliant, though a little more muted to allow the showstopping gown to take the centre stage. She opted for a predominantly black ensemble outside of the dress, including a belted wool coat from Max Mara, which was also previously worn by her mother. Accessory-wise, she kept it simple with a black satin clutch from European royal favourite Gianvito Rossi, and a pair of black suede heels from Aquazzura. Very chic!

In the royal style blogger's comment section, fans were in love with her look. One wrote: "Love that she is wearing a dress first worn by her grandmother! Beautiful dress and the colour looks great on her," while another commented: "This is sans doute the best re-imagining of a vintage dress I have ever seen. Simply delightful in every way. Brilliant!"

Meanwhile, others commented on the timelessness of the garments, with a third follower adding: "This is why dressing in classic style is the best. You can rewear an outfit for decades." Another questioned how the piece has remained so pristine, writing: "How on earth does a dress last that long in such good condition? Ah, to be royal…"
