Jennifer Lopez shares ‘first peek’ at Ralph Lauren turtleneck wedding dress

Jennifer Lopez is finally giving fans a close-up look at her wedding dress.

The pop superstar, who married Ben Affleck (again) in a lavish all-white celebration in Georgia Saturday, shared a “first peek” at her bridal gown on Instagram Tuesday morning.

Lopez, 53, walked down the aisle wearing a custom Ralph Lauren creation with short sleeves, a cutout back and a ruffled train, amping up the drama factor further with a show-stopping cathedral-length veil carried by the couple’s children: J.Lo’s twins Max and Emme, 14, and Affleck’s kids Violet, 16, Seraphina, 13, and Samuel, 10.

And the “On the Floor” singer’s close-up snap offers a glimpse of the gown’s frilly turtleneck detail and sheer veil, as well as the pearl-and-diamond Mikimoto earrings, silvery smoky eye makeup and nude lip she selected for the ceremony.

“First peek at my wedding looks at OnTheJLo.com,” Lopez captioned the pic, suggesting she wore multiple looks on her big day — although two hours after she posted, eager fans still hadn’t received their newsletters.

Page Six was the first to report that Lopez would get hitched in a dress by fellow Bronx native Ralph Lauren.

And the bride wasn’t the only one in a look by the American designer over the weekend: her ex Alex Rodriguez (who didn’t attend the Bennifer nuptials) posted an Instagram “fit check” showing off his all-denim Ralph Lauren duds Friday.

The “Let’s Get Loud” hitmaker first tied the knot with Affleck, 50, in a low-key Las Vegas ceremony in July, and again wore a duo of white dresses to mark the occasion: an off-the-shoulder Zuhair Murad lace number with long sleeves, a fishtail train and a matching lace-trimmed veil, and a sleeveless floral jacquard Alexander McQueen gown Lopez said she’d “been saving” for “so many years.”
