All the Looks From Tiffany & Co.'s Lavish Reopening Party

Iconic luxury jeweler Tiffany & Co. reopened its Fifth Avenue flagship last night, and marked the momentous event with a grand, star-studded party. At The Landmark, guests dressed in their most elegant gowns were able to peruse through the brand's dazzling diamond collection before walking the Tiffany-blue carpet to the after-party.

Blake Lively, Hailey Bieber, Florence Pugh, and Anya Taylor-Joy were among the stars who gathered at the bash to celebrate the luxury brand—and to see Katy Perry perform. The singer surprised the audience by making an appearance with the Radio City Rockettes—another New York City staple. Dressed in Tiffany's signature blue, she sang her biggest hits, including "I Kissed a Girl" and "Eye of the Tiger."

Ahead, see every celebrity red-carpet look from the night.
