Princess Eugenie turned 29 on Sunday and, in honor of the milestone, Zac Posen—the designer of her second wedding dress—shared a never-before-seen photo of the stunning ensemble to Instagram. Posen's post came with a sweet message: "Every now and then you meet somebody who just knocks your socks off. This last year I got to know a young lady who possessed natural elegance, a heart of gold and sophisticated humor," he wrote. "My studio and I had the honor (and the best time) collaborating with her on her special gown. Best of all she is dedicated to using her privilege to help our world and its people with her project @the_anti_slavery_collective. Happy Birthday!"
It's clear that Princess Eugenie feels the same way about Posen. She referred to the American designer as "such a cool, fun, brilliant designer and friend" in an audio recording that accompanied a royal exhibition (her wedding dresses are currently on display at Windsor Castle, alongside Meghan Markle's). Though we've seen a photo of Eugenie in the custom Champagne-hued gown before, this marks our second look at what we thought was a champagne-hued gown—turns out, it was actually a peachy-pink! Her colorful party look was drastically different from the white, off-the-shoulder Peter Pilotto number she sported during her ceremony—but it was equally as stunning.
As for the inspiration behind the royal's second garment? When Princess Eugenie approached the American designer, she explained that she was moved by old-Hollywood glam. "I wanted something reminiscent of Grace Kelly in To Catch a Thief, so I showed that for reference and Zac came up with this silk that he'd found from Manchester. Every single draping effect, every single detail, every button, it's all painstakingly done by him and his team," she revealed in the audio recording, reports Town & Country.
You can see the look for yourself while visiting Windsor Castle's Grand Reception Room. Both of Eugenie's dresses are available to the public, as is the Greville Emerald Kokoshnik Tiara, which she wore during her ceremony; the headpiece was a gift from her grandmother, Queen Elizabeth II.
