The actress wore an ivory caped dress by designer Jenny Packham and shared all of the details in a video with Vogue.
"So fun to talk about my beautiful dress and how it came to be!," the "Younger" star wrote in an Instagram caption.
During the video clip, Duff gives fans a behind-the-scenes look at her final fittings just a few days before the wedding as she mentions that her dress was stuck in London.

The video begins with Packham giving a glimpse of the sketches created of Duff's wedding dress and discusses the process.
"I want Hilary to feel how I think she wanted to feel in this dress from the direction that we had which is very modern and it's quite a bold look, and more than anything I want her to feel immensely confident in it. It is a very confident look," said Packham during the video.
A few unique details included high padded shoulders, elongated flowy cape-like sleeves, an open back from the neck down to the waist, and 100 buttons from the waist down to the hem.
The dress also included embroidery close to the hem with her, Koma's, and their children's initials.
Duff completed her look with a middle-parted wavy hair look and a jeweled headband styled by her go-to hairstylist Nikki Lee.
