Kylie Jenner’s 26th birthday dress is covered in cutouts

This LBD has some serious style cred.

Kylie thanked fans for their sweet messages after she turned 26 on Thursday, sharing an Instagram post that showed off her sexy black party dress as she celebrated on a yacht.

“thank you for the birthday wishes 🤍🤍🌎 forever grateful ⚓️” the reality star captioned the series of photos.

In the pics, she sports a form-fitting black halter dress with a low back that dips down into a row of rosette-accented cutouts — and her birthday look actually has a tie to the “Real Housewives” franchise.

The vintage Jean Paul Gaultier creation came from Nou Studio, the vintage designer boutique owned by “Real Housewives of New Jersey” star Dina Manzo’s daughter, Alexia Ioannou.

While Jenner only gave fans a look at the back of the archival frock, Ioannou, 27, shared photos of herself wearing the design in July that revealed the sleek and simple front with a plunging neckline.

The Kylie Cosmetics founder’s dress also resembled a backwards version of the controversial cutout wedding guest look sister Kendall Jenner wore in 2021.

Kylie — who is currently dating Timothée Chalamet — kept the rest of her look simple, wearing her hair in a slicked-back bun and adding tiny gold earrings and several layered bracelets.

“Happy Birthday beauty queeeen ✨✨✨” Lori Harvey commented on the post, while Lala Kent added, “Happy birthday ❤️❤️❤️‼️‼️‼️😘😘”

Meanwhile, Dina Manzo weighed in on Nou’s Instagram post sharing Kylie’s birthday dress, with the “Housewife” writing, “So good!!! Looks incredible on her! 💗💗💗”

Along with her little black dress, the mom of two also wore a black birthday bikini on Thursday as she took her celebrations to the beach, wearing a mesh style with a brown layer underneath and a thong bottom.

While it looks like Jenner is soaking up the sun on a yacht and shared photos of turtles for her birthday beach vacation, we can only hope there are more sexy styles to come.
