For years fashion critics and royal watchers alike have marvelled at the sartorial love affair between Catherine, Duchess of Cambridge and British designer Jenny Packham.
The duchess has been wearing Jenny Packham gowns since her very first days as a fully-fledged royal and has continued to work with the designer over the last decade.
The synergy and creative vision shared between the two women shone on Wednesday night, when Catherine stepped out in one of her most regal Jenny Packham gowns to date.
Attending a dinner hosted by the Governor General of Jamaica at King's House with husband Prince William, the 40-year-old royal stole the show in the floating green tulle number.
Featuring a cinched bodice decorated with glittering embellishments along the waist, the full princess-style skirt fell elegantly to the floor and trailed behind her.
It was the shimmering ruffle detail along the neck that caught every eye in the room, however, baring the duchess' shoulders in a rare step away from more modest necklines.
Catherine chose to go without a necklace or pendant, instead accessorising with delicate cameo brooch featuring a small portrait of the Queen set against a vibrant yellow ribbon.
She also wore regal gold, diamond and emerald drop earrings with a matching bracelet, both of which were on loan to the duchess from the Queen's vast jewellery collection.
To complete the look, the pinned her Royal Family Order and GVCO Star to her waist and swept her hair into a sleek updo.
The stunning ensemble is yet another style highlight from Catherine and William's royal tour of the Caribbean, with the pink The Vampire's Wife gown she wore in Belize also making headlines.
But this green number goes one step further, embracing the classic 'princess gown' look for the couple's fifth night abroad.
Welcomed to the dinner by local Governor General Patrick Allen, Catherine and William assured him they had a "fantastic day" of events in Jamaica, after arriving on Tuesday.
Over on social media, royal fans commented on how regal Catherine looked in the gown, several noting that the silhouette was reminiscent of one Princess Diana wore in 1981.
They pointed to a delicate Beville Sassoon dress the late Princess of Wales wore to an art exhibition at the Victoria and Albert Museum during her marriage to Prince Charles.
Both gowns feature full skirts, cinched waists and off-the-shoulder designs, and both are made of light, flowing fabrics.
Of course, Catherine has very much made a name for herself as a royal fashion icon apart from her late mother-in-law's style legacy too.
Her green dress is just her latest sartorial victory in partnership with Jenny Packham, who has long been one of the duchess' most beloved designers.
