Just over a month after Princess Eugenie and Jack Brooksbank tied the knot at St George's Chapel in Windsor, Zac Posen has shared two never-before-seen images of the royal's second wedding dress.
After walking the aisle in a bespoke Peter Pilotto gown, the royal changed into a blush pink number by the American designer.
But due to the private nature of the function held at the Royal Lodge in Windsor, the newlyweds' official portraits - taken by fashion photographer Alex Bramall - only depicted the front of the dress.
Yesterday, Posen finally revealed the back of the now-famous gown for the first time via Instagram and it's given royal fans an even closer look at the bespoke garment.
The designer took to the social media platform to share two intimate shots from inside his New York-based atelier alongside the caption: "The back by popular demand, before the final #whiteroseofyorkembroidery was placed. In the #HouseOfZ #atelier #zacposen."
Like her wedding gown, the second dress also featured a plunging back - a sartorial move designed to showcase her scars from childhood scoliosis surgery.
An official Buckingham Palace statement explained that Princess Eugenie is inspired by the "beauty of Windsor and the surrounding countryside" therefore the evening dress was crafted from a powder pink hue to reflect the English rose.
As shown in the newly-released images, the silk gown also featured delicate buttons down the back with a sheer cape to finish. In a subtle nod to her roots, the White Rose of York was also embroidered on the shoulders and back of the gown.

To accessorise the evening ensemble, Princess Eugenie wore diamond and emerald drop earrings, a wedding gift from Brooksbank, while a hair slide once worn by Queen Victoria finished the look.
On designing the 28-year-old's wedding reception dress, Posen said in an official statement: "It was an incredible honour to create this dress for Her Royal Highness Princess Eugenie on her wedding day."
"Her grace, elegance and strength perfectly embody everything I could hope for in a woman wearing our design," he added.
