The second gown she wore on the day featured a bias-cut pin-tucked plissé in a pale pink color, reminiscent of the color of an English rose.

In the caption of his Instagram post, Posen wrote: "A fairytale weekend I will never forget." He added the hashtag "white rose of york."

The photo showed white embroidered roses on the pale pink material, but Posen didn't clarify if it was part of the dress or whether he designed it as wedding favors.

His fans took to the comment section, with Caroline Weber said the detail was "unreal," while another user described it as "pieces of art."

Princess Eugenie's main wedding gown was designed by Peter Pilotto and Christopher De Vos and sported low-back to show Eugenie's scoliosis scar.

Eugenie underwent an 8-hour operation when she was just 12 years old, during which specialists inserted rods and 1.5-inch screws into her spine.

Apart from being living proof that the groundbreaking operation worked, she has committed herself to raise awareness about the condition.

The fabric of her wedding dress also hides hidden symbols which carry special meaning, such as the Thistle of Scotland.

The embroidery also featured a Shamrock for Ireland which pays tribute to Eugenie's family on her mother's side.

She also wanted the York Rose to be included, which represented the family's home. Her outfit was completed with the Greville Emerald Kokoshnik Tiara.

The tiara was made by Boucheron in 1919 and belongs to Eugenie's grandmother, the Queen. It also sports a 93.70-carat emerald.

As reported by Independent, her wedding ceremony incorporated both modern and traditional elements, balanced for the perfect fairytale wedding.
