The 'Euphoria' star was joined by many of her famous friends for the soiree.
Sydney Sweeney is going back in time! The celebrated actress celebrated her 26th birthday in style -- specifically, the style of the 1980s.
To commemorate her special day, the Euphoria actress went back to high school via metaphorical time travel, and threw an elaborate '80s-prom-themed birthday bash with REVOLVE at Serra on Vine in Los Angeles, California, with a guest list filled with her famous friends.
The hall was decked out in multiple mirror balls and long, flowing pink curtains draped down from the ceiling, flawlessly recreating the over-the-top elegance and shimmering glory of a true '80s prom.
The guests all took the theme seriously as well, rocking their best and most era-appropriate retro look for the festivities.
The birthday girl herself went all out as well, doing up her hair in big, voluminous blonde curls while rocking a hot pink minidress with wildly puffy sleeves, a Self Portrait Capri Micro Bag, Nalebe Dimante Slingback heels, Elizabeth Cole Ariana Earrings, and Elizabeth Cole Danika Necklace from REVOLVE.
Sweeney posted snapshots from the prom party to her Instagram, reposting many pics shared by her famous friends -- who included Camila Mendes, Ariana Greenblatt, Alexandra Shipp and Nicola Peltz, to name just a few.
All the guests were also on hand to watch Sweeney blow out the candles on her massive three-tier birthday cake.
Meanwhile, less than a week after winning the award for Best Latin Video at the 2023 MTV VMAs, Anitta also came to celebrate Sweeney's party, and was excited for a chance to participate in the fun retro nostalgia.
"My first prom Thanks to the bday girl," Anitta captioned a photo of herself and Sweeney at the party. "U deserve the best!!!"
