Sydney Sweeney’s 26th birthday bash was totally rad.
The “Euphoria” star celebrated the milestone with an ’80s prom-themed party at Serra on Vine in Los Angeles Saturday — and celebrity guests like Anitta, Camila Mendes, Nicola Peltz, Tan France and Dylan Mulvaney came dressed to impress.
Sweeney was the star of the show in a hot pink corseted minidress complete with the statement sleeves, dropped waist and puffed skirt typical of the decade.
She accessorized with a matching bedazzled Self-Portrait mini bag ($480), bow-topped Nalebe slingbacks ($750) and an Elizabeth Cole necklace ($373) and earrings ($138) set with pink crystals — all provided by Revolve, which hosted the stylish star’s retro soirée.

And Sweeney looked every inch the prom queen thanks to her era-perfect perm (courtesy of hairstylist Glen Oropeza) and shimmering pink makeup look (created by artist Melissa Hernandez).
The birthday girl wasn’t the only one who understood the sartorial assignment; “Riverdale” star Mendes, with whom Sweeney shares stylist Molly Dickson, arrived in a bubble-skirted scarlet Aknvas mini teamed with black tights.
Anitta showed up in a second-skin lamé look and side-swept waves, and shared a snap with the lady of the hour on her Instagram Stories, noting that it was her “first prom.”

The venue was decked out with disco balls, pink balloons, festive streamers and a lit-up dance floor for “Syd’s Prom,” and Sweeney blew out candles on a massive three-tiered birthday cake during the fête.
Other big names in attendance included “Barbie” actresses Ariana Greenblatt and Alexandra Shipp — who stars alongside Sweeney in “Anyone But You” — as well as “Euphoria” makeup artist Donni Davy.
