On Thursday evening, Tiffany & Co. celebrated the reopening of its newly revamped New York City flagship location on 57^th Street and Fifth Avenue, now known as “The Landmark.” A-list guests including Hailey Bieber, Blake Lively, Zoë Kravitz, Florence Pugh and Gabrielle Union to name just a few saw the The Landmark before moving to the fashionable fête at the Tiffany Flagship Next Door – the jewelry house’s previous interim flagship store.

All drenched in dazzling Tiffany & Co. jewels, attendees and friends of the house like Anya Taylor-Joy, Pharrell Williams, Eileen Gu, Gal Gadot and Michael B. Jordan were serenaded with an opening set by DJ Mia Moretti, followed by a performance from the Radio City Rockettes.

The exclusive party’s headlining performance came courtesy of Katy Perry, who wore a Tiffany blue strapless dress after walking the red carpet in a cream-colored ruffled vintage Christian Dior gown. Mark Ronson followed Perry with a rousing DJ set to close out the evening.

Other notable guests included Dwayne Wade, Brooklyn and Nicola Peltz Beckham, Tracee Ellis Ross, Barbara Palvin, Dylan Sprouse, Lauren Santo Domingo, Jacob Elordi, Marc Jacobs, Martha Stewart, Athena Calderone, Anitta, Gayle King, Baz Luhrmann, Tiffany Haddish and more, wearing designs from Tiffany & Co. of course.
