Queen Máxima dripped in pearls at a Middelburg-based event with her husband King Willem-Alexander and mother-in-law and Princess Beatrix on 11 April and she could have easily passed as a bride.
The Argentinian-born Dutch royal, 52, was spotted at the Four Freedom Award Ceremony at the Abbey looking incredible in a stunning ivory two-piece set from Natan Couture in a heavy textured fabric.
Her co-ord consisted of an Audrey Hepburn-esque A-line skirt with a matching suit jacket with a super cinched waistline and an open-collared neckline.
Adding to the vintage bride aesthetic were her enormous pearls adorning her neckline and ears, as well as her statement Princess Beatrice-worthy headband. She also carried a chic envelope clutch by Natan Couture in a neutral hue and wore nude heels from Gianvito Rossi, the 105s.
She even wore cream gloves with a vintage feel. Máxima's hair was worn in a gorgeous bridal-worthy updo at the nape of her neck. Meanwhile, Máxima's makeup was radiant with a natural glossy lip and a dark smokey eye.
She posed with her husband who looked smart in a dapper navy suit, and Princess Beatrix who looked splendid in a navy ensemble with a statement hat and unconventional cornflower blue eyeshadow.
It is not the first time that the royal has wowed in a wedding-worthy ensemble. Máxima looked like a goddess at the Iris van Herpen: Sculpting the Senses exhibition at Musee Des Arts Decoratifs in Paris last November.
She wore a floor-grazing ivory pleated gown with a sheer high-necked bodice in a neutral pattern. The caped number was styled with showstopping diamond-encrusted accessories and a low chignon in her sandy blonde hair.
HRH also chose to wear bridal white to King Charles' coronation last May. The mother-of-three arrived at Westminster Abbey alongside her husband looking like a dream in a crisp white A-line dress with a sheer floral panel across the décolletage and shoulders.
Her look was cinched at the waist with a diamond buckle and she wore cream gloves, nude heels, and breathtaking diamond drop earrings. The Queen also wore a bright white fascinator and styled her hair in loose Hollywood waves.
Máxima got married herself in 2002, looking like a vintage Hollywood star in Valentino. The royal was seen in an ivory high-necked raw silk gown with three-quarter-length sleeves with lace detailing.

Her hair was worn up with a gorgeous polka dot veil attached. The star of the show was her tiara which, according to The Court Jeweller, "combined the diamond festoon base of the Pearl Button Tiara with a set of diamond stars from the family collection."
