If we could go back and relive our prom night, there's an approximately 100% chance it still wouldn't be as fun as the one hosted by Alice + Olivia on June 15th in honor of the label's 20th anniversary (officially designated as "Alice + Olivia Day" by NYC mayoral proclamation!).

From a glittering basketball court and neon graffiti-painted lockers to chic bleachers and, of course, a funky dance floor, the al fresco fete saw the High School experience recreated in A+O's signature glamorous, and joyously colorful, style.

The woman of the hour, founder, CEO, and creative director Stacey Bendet, was joined by A-list friends and loyal fans of the brand including Nicky Hilton Rothschild, Ariana DeBose, Lea Michele, Busy Philipps, and AnnaLynne McCord for the occasion. Fashion world It Girls like Kit Keenan and Ella Emhoff were also on hand to explore the interactive activations and strike a pose among the many, many photo ops (including a Polaroid wall of class superlatives).

Throughout the evening, guests enjoyed specialty cocktails by Absolut Vodka and Olmeca Altos Tequila, delicious vegan bites by Beatnic, music and performances by Gracie Abrams, and DJ KISS, and dancers choreographed by Ebony Williams and Deijah Robinson. By the end of the night, the crowd could be found getting their groove on under the stars.
