Sydney Sweeney’s not done celebrating the world’s most talked-about newlyweds just yet.

On Saturday, the stylish “Euphoria” star headed to Jeff Bezos and Lauren Sánchez’s post-wedding pajama party in Venice, Italy, wearing a black lace gown by Galia Lahav that accentuated her bust.

She wore her blond tresses down in long, loose waves and paired the glam look with minimal jewlery.

Sweeney, like Kendall Jenner and Kylie Jenner, appeared to be one of many stars to elevate the dress code. Guests were asked to interpret the pajama theme with their own version of elegant loungewear.

For Friday’s ceremony, Sweeney went full princess in a strapless blush gown with a twisted sweetheart neckline, which she paired with soft, center-parted waves and a pretty pear-cut diamond necklace.

Ahead of the nuptials, the “Anyone But You” actress was spotted strolling around the city’s canals in a frilly black Chloé romper accessorized with a vintage Chanel bag, Miu Miu slingbacks and L’Atelier Nawbar hoop earrings.

Sweeney was also present and accounted for at the couple’s welcome soirée on Thursday, dressed in a vintage Elie Saab Haute Couture halter gown awash in feminine ruffles and blush-toned beadwork.

Stylist Molly Dickson teamed the Emmy nominee’s archival attire with a pair of show-stopping Anabela Chan earrings set with lab-grown Begonia pink sapphires and simulated white diamonds.

Other stars in attendance at Bezos and Sánchez’s over-the-top wedding weekend include Oprah Winfrey, Ivanka Trump, Jerry and Jessica Seinfeld, Leonardo DiCaprio and most of the Kardashian-Jenner family.

Page Six exclusively reported that DJ Cassidy is set to perform at tonight’s pajama-themed party, which is set to take place at the historic Arsenale di Venezia.

“We have incredible music planned,” Sánchez told Vogue of the bash, where phones will be prohibited. Guests will be given slippers so they can dance the night away pain-free — blue velvet Vibi Venezia versions for men, black open-toe ones from Amazon for women.

Sweeney, who’s famously fond of comfy shoes, will surely appreciate the gesture.
