Sydney Sweeney is living it up.

The “Euphoria” actress posted new beachfront pics, wearing a vintage Christian Dior by John Galliano pinup-style minidress.

The 2000 style recently sold for nearly $9,000 on resale site 1stdibs and features an off-the-shoulder neckline and baby pink monograms.

The actress looked radiant in the photos taken by Amber Asaly and posted on her Instagram on Friday. She sported a vintage outfit, complemented by natural makeup and her hair styled in effortless beach waves, showcasing a joyful demeanor.

In one image, the 27-year-old plays on the sand dunes while rocking a matching pink Dior bucket hat.

Fans are captivated by her newfound radiance, especially in light of recent rumors about Sweeney and her fiancé, Jonathan Davino, 41, reportedly canceling their wedding and focusing on improving their “turbulent” relationship.

“Single life looks good on you 😍,” one fan commented, with another adding, “Wow you’re looking so beautiful and gorgeous ❤️❤️❤️❤️❤️.”

The post marks the second time this week that Sweeney has channeled her inner mermaid.

The day before, the star was seen taking a refreshing plunge, dressed in a white lace bikini top and thong bottom from Fae x Revolve. She shared moments from her pool escapade, beautifully captured by Asaly, on her Instagram account.

She captioned the photos and video of herself floating beneath the water’s surface in the denim-trimmed two-piece with a single wave emoji.

“The most magical mermaid,” Asaly commented, while Paris Hilton wrote a mermaid emoji.

An insider told Us Weekly that Sweeney and Davino are still together for now.

“Sydney and Jonathan have been having major issues but are not fully split,” the insider said.“Things are not great right now, but they aren’t throwing in the towel yet. They are working on their relationship but have called off the wedding for now.”

The couple, who have been dating since 2018, were reportedly meant to tie the knot this spring.
