Zac Posen has shared unseen photograph from Princess Eugenie's, 30, wedding.
The designer, who crafted Eugenie's second gown, posted the image yesterday.
Said: 'It was so special creating this gown for this wonderful moment in your life'.
Designer added: 'Wishing you love always with your new baby angel on the way'.
Shared the snap on royal's two year anniversary to Jack Brooksbank, 34,.
The couple announced they are expecting their first child together last month.
Princess Eugenie's wedding dress designer has shared a previously unseen photograph from the royal's big day online.
The Queen's granddaughter, 30, wore the stunning peach-hued gown by Zac Posen to her evening reception in October 2018, after opting for a white low-back dress by Peter Pilotto for her church wedding to Jack Brooksbank, 34.
The American designer posted an unseen picture from the wedding online yesterday as the couple celebrated their second anniversary, writing: 'It was so special creating this gown for this wonderful moment in your life, being with you and the family on the magnificent magical day, I will remember forever.'
It comes after Princess Eugenie, who is expecting her first child with Jack in the spring, shared a series of previously unseen wedding photographs as she posted a gushing tribute to her husband Jack Brooksbank.
The candid picture shows Eugenie standing with Jack at their wedding reception and beaming at one another as they posed for photographs.
Sharing the snap, Zac wrote: 'Happiest 2nd Anniversary dear Princess Eugenie & Jack!'
He added: 'Wishing you both continued love and happiness always with your new baby angel on the way.'
Yesterday, Princess Eugenie marked her second wedding anniversary by posting an Instagram video online showing a compilation of unseen holiday photographs and wedding snaps while the song 'Baby It's You' by indie band London Grammar played in the background.
Among the images were three pictures from their October 2018 wedding which have not been shared with the public before, including a snap of Eugenie and Jack, 34, sharing a laugh with one another after the ceremony.
Sharing the post online, Princess Eugenie, who is expecting her first child with Jack in the spring, wrote: 'Been the best 2 years married to you and 10 years with you in total.. happy memories always my dear Jack.'
In one of the photographs, which was taken from behind, the newlyweds could be seen enjoying a kiss after the ceremony while in another, they beamed as they posed in one another arms.
Other pictures shared in the compilation included holiday photographs of the couple from over the years, with one showing them posing alongside a huddle of penguins.
Their wedding anniversary comes weeks after the Queen's granddaughter and her husband of two years Jack announced they are expecting the baby in early 2021.
A friend of the couple told People that while the 'fun' royal will likely be 'more of a bohemian parent', Jack is likely to be the 'calm and chilled' influence.
Speaking to Vanity Fair's Katie Nicholl, a family friend also claimed titles 'don't matter' to the couple, adding: 'Eugenie knows that a title can be a curse as well as a blessing and she and Jack want their child to live an ordinary life and eventually work to earn a living.'
Sources also said the couple will choose an 'ordinary' name for their first born.
The source said even if the Queen offered a title as a gift, it was 'not Eugenie or Jack's desire' for their child to have a title.
Despite having royal titles, Princess Eugenie and her sister Princess Beatrice are not currently considered to be senior working royals, because they do not carry out duties full time on behalf of the Queen.
Princess Eugenie works as a director for Mayfair-based gallery Hauser & Wirth and receives no money from the Queen.
Meanwhile Jack, who is European brand manager for Casamigos Tequila co-founded by George Clooney does not have a title or an HRH.
Eugenie and Jack's child will be 11th in the order of succession, which means the Queen's youngest son Prince Edward will slip down a place into 12th place.
The baby will be the first grandchild for Prince Andrew and Sarah Ferguson, and will be the Queen and the Duke of Edinburgh's ninth great-grandchild.
Sharing the news on Instagram last month, Eugenie wrote: 'Jack and I are so excited for early 2021....,' alongside photos of baby slippers and her and Jack smiling.
Eugenie and Jack, who spent lockdown at Fergie and Prince Andrew's home on the Queen's Windsor estate, have been seen out and about in recent weeks as they enjoy life in London ahead of welcoming their first child.
The happy news will no doubt be welcomed by grandfather-to-be Prince Andrew, 60, who remains plagued by controversy over his friendship with the late paedophile Jeffrey Epstein and Ghislaine Maxwell, who was arrested for her role in allegedly procuring young girls for the financier.
