The Duchess of Sussex worked closely with Waight Keller on the design of the silk organza dress, which featured an off-the-shoulder neckline and three-quarter length sleeves, Kensington Palace announced at the time.
Chloe Savage, who worked on the embroidery for both Meghan Markle and Kate Middleton's wedding dresses, said the neckline on Markle's dress was designed to show her personality.
"Every bride's dress is a statement of themselves," Savage previously told Insider's Anneta Konstantinides. "A good wedding dress designer will help you show off both your figure and everything about you to the best — and that's what those dresses did."
"Meghan's is more flashy," she added. "Off-the-shoulder was far more risqué, but she's a risk-taker by comparison."
"I had a very clear vision of what I wanted for the day, and what I wanted the dress to look like," the duchess said of the dress a few months after the wedding, Harper's Bazaar reports.
"So what was amazing in working with Clare is that sometimes you'll find designers try to push you in a different direction, but she just completely respected what I wanted to see for the day, and she wanted to bring that to life for me," she added.

Markle took part in the tradition of having "something old, something new, something borrowed, and something blue" to walk down the aisle with.
The duchess' "something blue" was sewn into her veil.
"Somewhere in here there's a piece of blue fabric stitched inside," Markle said during an appearance on the documentary, "Queen of the World," which aired in 2018. "It was my something blue. It's fabric from the dress that I wore on our first date."
3. The dress had only six "meticulously placed seams" so that it would sit effortlessly on Markle's frame
As Insider previously reported, Givenchy said the gown was crafted with only "six meticulously placed seams" so that it would sit effortlessly on Markle's frame.
"The graphic open bateau neckline gracefully frames the shoulders and emphasizes the slender sculpted waist," Givenchy said in a statement at the time.

The silk veil — which took almost 500 hours to craft — was embroidered with California poppies, the national flower of Markle's home state.
It was also embroidered with flowers representing all 53 countries of the Commonwealth, a tribute to her new role as a senior working royal.
"Over time we had different conversations back and forth, and I came up with the idea of representing each of the [53 Commonwealth countries]… through their flora. And we both loved the story of that," Waight Keller said in a pooled interview two days after the wedding, Harper's Bazaar reports.
"It also meant that every single one of those countries also journeyed up the aisle with her. It was a really poetic moment. She absolutely loved it," she added.

The veil was also embroidered with an additional flower, Wintersweet, which grew in front of the couple's former Nottingham Cottage home, Harper's Bazaar reports.
Markle and Harry resided in the cottage in the grounds of Kensington Palace in London until 2019, when they relocated to Frogmore Cottage in Windsor before subsequently moving to California in 2020.
