Thursday night’s Tiffany Blue Book Gala featured a bevy of high-profile stars, friends of the American jewelry brand and more sporting pieces from the latest edition of the high jewelry collection at Park Avenue Armory in New York City.

Teyana Taylor, Naomi Watts and more merged high fashion with high jewelry, wearing designs from American brands like Calvin Klein and Marc Jacobs to Sabina Bilenko and Oscar de la Renta, among others. WWD breaks down those looks and more ahead.

Rosé

Blackpink member Rosé opted for a design by New York City-based brand Khaite. The ethereal look hailed from the label’s fall 2026 ready-to-wear collection, which debuted as part of New York Fashion Week in February. The sleeveless white dress featured a lacy bodice with ornate detailing and full, tulip silhouetted skirt. A black bow was added at the waist for added definition and a contrasting color touch. Rosé wore pointed toe white pumps with her dress and accessorized with a Tiffany & Co. necklace.

Teyana Taylor

Teyana Taylor turned to Calvin Klein for her attire. The Oscar-nominated “One Battle After Another” star wore a look from the American designer’s fall 2025 ready-to-wear collection — a voluminous coat with dark feathery detailing throughout. Taylor accessorized the look with Tiffany & Co.’s diamond palm necklace.

Amanda Seyfried

Amanda Seyfried shimmered from head to toe in a minidress by Oscar de la Renta. The long-sleeve look featured a scoop neckline, all-over glittering details in an icy blue tone and a slightly scalloped hem at the skirt. “The Testament of Ann Lee” star also wore metallic silver heels by Gianvito Rossi and accessorized with sapphire and diamond jewelry pieces from Tiffany & Co.

Naomi Watts

Naomi Watts wore a sleeveless black gown by Taller Marmo. The fall 2026 collection look featured textural contrast, with a feathery skirt and extra plumage at the hips, contrasted with the base black fabric of the bodice. Watts added a touch of sparkle to her look with turquoise and diamond earrings and a coordinated necklace by Tiffany & Co.

Greta Lee

Greta Lee opted for a design by Marc Jacobs. The “Past Lives” actress and Tiffany & Co. campaign star turned to the America couturier’s spring 2026 ready-to-wear collection, which debuted as part of New York Fashion Week in February. The look featured a strapless shimmering blue cropped bodice with a high-waisted black maxiskirt. The actress wore a pair Gianvito Rossi black pointed toe pumps and accessorized with a jade Tiffany & Co. statement necklace.

Diane Kruger

Diane Kruger channeled mermaid style inspiration with her intricately designed Sabina Bilenko dress. The strapless gown, which hails from the label’s spring 2026 couture collection, featured a scalloped blue skirt with strands of bead work mimicking waves and a semi-sheer bodice embellished with ornate beadwork. Kruger added aquamarine and diamond Tiffany & Co. earrings, ring, bracelet and necklace to accessorize her look.

The 2026 Tiffany Blue Book Gala celebrated the latest edition of Tiffany & Co.’s Blue Book Collection. The newest iteration took inspiration from the Hidden Garden, spotlighting the American brand’s legacy in gemstones and continued pursuit of artistic design.
