Did Kelsey Merritt and Chace Crawford Just Make Their Official Public Debut as a Couple?

The Blue Book gala marked the unveiling of Tiffany & Co.’s latest high jewelry collection, a continuation of the jeweler’s deep-rooted connection to nature’s most enigmatic wonders. For 2025, the maison drew inspiration from the mysteries of the sea—think intricate coral motifs, organic wave-like forms, and a color palette rich in sapphires, diamonds, and opals. The event itself was set against the historic grandeur of the Met’s Greek and Roman halls, transformed for the evening into a luminous undersea world, with a high-wattage guest list to match. 

Kelsey epitomized modern-day glamour in a black velvet gown from the Dior Cruise 2025 collection. The dress, with its clean square neckline, cinched waist, and floor-skimming full skirt, exuded quiet sophistication. The plush velvet fabric offered a rich, tactile depth that felt opulent yet effortless—perfectly aligned with the evening’s intimate atmosphere. "Felt like a princess," she wrote on Instagram, describing her formal look that's a masterclass in understated drama.

Elevating her look further, the model wore Tiffany & Co. high jewelry, notably including the exquisite Wisteria necklace from the brand’s Botanica collection that was first introduced in the 2022 Blue Book. Crafted from chalcedony, sapphires, diamonds, and platinum gold, the intricate piece rested delicately around Kelsey's neck, a perfect match to her classic black gown. Complementary diamond pieces from Tiffany & Co. completed her ensemble, glistening under the gala’s dramatic lighting.

Beside her, Chace looked every bit the dapper gent in classic menswear with a subtle contemporary twist. The actor suited up in Brunello Cucinelli, wearing a sharply tailored black tuxedo with a sleek satin lapel. The Gossip Girl star's crisp white shirt, classic black bowtie, and polished black shoes anchored the look in tradition, but he added a distinct touch with a Tiffany & Co. brooch pinned onto his lapel—a subtle accessory as a chic nod to the event’s jeweler host.
