Sheer glamour!

Jennifer Lopez showed off a sexy sheer dress in series of Instagram photos posted on Thursday, Aug. 15, which also happens to be her husband Ben Affleck’s 52nd birthday. In the snaps, the 55-year-old star poses in front of a dark gray car on a tree-lined street.

The gown, which is presumably Dior given Lopez’s one-word caption, is a sheer wrap design with a black belt tied around the waist and silver embellishments in a vertical pattern. One photo shows the Atlas star sitting on the hood of the car, revealing the dress’ daring thigh-high slit.

To accessorize her glam ensemble, Lopez wore black platform sandals, a sparkly bucket-style purse and dangling earrings. Her hair was pulled back into a sleek ponytail and she rocked her usual soft smoky makeup look.

Lopez’s fans did not hold back from hyping her up in the comment section of the post.

“Absolutely STUNNING! ❤️😍 No One Does it like you 🥹,” one user wrote.

“Yaaas queen 🔥 living your best life, beautiful as always! I love you Jen 💞,” said another.

A third wrote, “Class and elegance ✨👑✨”

Last week, Lopez’s stepdaughter Violet Affleck paid homage to the star’s iconic sense of style.

The 18-year-old daughter of Ben and Jennifer Garner stepped out on Friday, Aug. 9 in what looks to be the same Dolce & Gabbana dress that the This Is Me…Now star once wore for a date night with Ben.

While taking a stroll in Brentwood, Calif., Violet was spotted wearing the pink-and-white chiffon gown with long sleeves, romantic pleating and a wrap neckline. The teen opted for casual footwear and red-and-white sneakers with half crew socks.

Lopez had previously worn the dress for a 2023 Valentine’s Day date night with husband Ben. She added gold accessories as well as a white belt adorned with the Dolce & Gabbana logo. The star’s hair was slicked back into a sleek ponytail.

Amid reports of tension in their marriage, the couple has spent the majority of the summer apart, including their two-year wedding anniversary on July 16.

Lopez vacationed in both Europe and the Hamptons, New York while Ben was in Los Angeles filming his upcoming sequel The Accountant 2 in Los Angeles.
