The model married singer Justin Bieber in a lavish ceremony in South Carolina at the end of September, following their low-key and private first wedding in 2018.
While Justin released images from the big day shortly afterwards, Hailey has now shown her "dream" dress to her 22.4 million followers in a series of posts on Instagram.
"Last Monday was the most special day of my life," she said, alongside a picture of the couple kissing, with Hailey wearing her dress and a train bearing the words, "Till death do us part".
Hailey wore several dresses at the celebrations; this one was designed by Off-White founder and Louis Vuitton Menswear artistic director Virgil Abloh.
In another post, she said: "@virgilabloh thank you for making my vision come to life and creating my dream dress. You and your @off____white team are incredible and I'm forever grateful I got to wear your beautiful creation."
More than 150 family and friends turned out to attend the couple's religious ceremony in South Carolina on 30 September, according to US media reports.
Celebrities including Kendall Jenner and Jaden Smith were among the party-goers pictured at the nuptials, with Ed Sheeran, Kylie Jenner, Katy Perry and Usher also said to be on the guest list.
