Jennifer Lopez wore three custom Ralph Lauren gowns to celebrate her wedding to Ben Affleck on Saturday—and they all had one eye-catching feature in common.

Lopez, 53, and Affleck, 50, married in Las Vegas in July, some 20 years after they first started dating and 18 years after they called off their engagement.

Last weekend, they celebrated their wedding in the grounds of Affleck's Georgia mansion, with loved ones including Lopez's 14-year-old twins Max and Emme, from her marriage to Marc Anthony, and Affleck's children with ex-wife Jennifer Garner: Violet, 16, Seraphina, 13, and Samuel, 10.

Details of Lopez's gowns have now been revealed, with Ralph Lauren sharing photos and sketches on Instagram that show all three dresses were backless.

The first gown, which the bride wore for a ceremony officiated by life coach Jay Shetty, was a "custom handkerchief wedding gown [that] reimagines a turtleneck column dress with the addition of a dramatic ruffle hem," according to a Ralph Lauren post.

"More than 1,000 hand-cut handkerchiefs and 1,640 feet of fabric were cut into ruffles and attached by hand, creating a voluminous, romantic skirt. Each handkerchief becomes a nostalgic keepsake and a modern heirloom, while the intricate constructed ruffled sleeves become a statement in craftsmanship and dignified design."

Per People, Lopez's second outfit of the day was a chandelier pearl gown, embellished with Swarovski crystals, pearls and micro-pleats of silk tulle. It reportedly took 30 artisans 700 hours to hand-embroider the dress.

The bride's third gown was cut to hug her curves in a mermaid silhouette, with a removable organza overlay serving as a high-fashion sheer hood. This dress was also embellished with crystals.

Affleck wore a Ralph Lauren Couture white tuxedo jacket, with black trousers and a bow tie. The couple's children also wore white Ralph Lauren outfits, according to People.

On Tuesday, Ralph Lauren released a one-minute YouTube video to showcase the intricacies of the gowns.

The clip, titled "The Making of a Moment With Jennifer Lopez," described the dresses as "modern heirlooms for a timeless romance."

The description went on: "In celebration of #JenniferLopez and #BenAffleck's wedding, #RalphLauren created the bride's three custom gowns with love, care, and consideration woven into every detail of the silhouettes."

Lopez's stylist Rob Zangardi also shared a closer look at the dresses on Instagram on Tuesday, describing the star as the "most beautiful bride there ever was."

Lopez teased a "first peek" of her wedding wardrobe on her own Instagram account on Tuesday, adding that there would be more to come on her On the JLo newsletter.

"The dresses were dreamy... thank you Ralph Lauren," Lopez wrote on her newsletter, alongside a series of sketches and photos.

"I will be sharing a few more pics and delicious details on our big day coming very soon On The JLo," added the actress, singer and dancer.

A host of celebrity guests attended the celebration in Georgia, with People reporting that Affleck's close friend and collaborator Matt Damon was there with his wife, Luciana Barroso.

Filmmaker Kevin Smith and his wife Jennifer Schwalbach Smith were also present, alongside Clerks actor Jason Mewes and his wife Jordan Monsanto. George Clooney and Renée Zellweger were also reportedly on the guest list.

After the couple's Las Vegas wedding, Lopez announced their marriage in her newsletter under the heading "We did it."

She wrote: "When love is real, the only thing that matters in marriage is one another and the promise we make to love, care, understand, be patient, loving, and good to one another. We had that. And so much more. Best night of our lives.

"They were right when they said, 'All you need is love.'

"We are so grateful to have that in abundance, a new wonderful family of five amazing children and a life that we have never had more reason to look forward to. Love is a great thing, maybe the best of things—and worth waiting for."
