While the couple later shared the intimate details of their proposal on Long’s Life is Short podcast, it was Bosworth’s impeccably curated ensemble—and a certain sparkling accessory—that first signaled their new chapter to the world.

Stepping out at the Wallis Annenberg Center for the Performing Arts on March 12, 2023, the Wonderland actress proved why she remains a perennial fashion icon.

She paired a textured Monique Lhuillier gown with Cicada jewelry, but for shoe enthusiasts, her red-carpet choices consistently serve as a masterclass in balancing femininity with high-fashion edge.

Since first sparking a connection on the set of the horror film House of Darkness, the pair has mastered the art of “couple style,” blending Long’s understated classicism with Bosworth’s penchant for avant-garde labels like Zimmermann and Chloé. He wore a streamlined, classic black suit by Berluti.

There’s a noticeable height difference between the couple—Justin Long stands at 5ft 9in, while Kate Bosworth is 5ft 5in—but Bosworth has long mastered the art of balance, often opting for heels that discreetly add lift beneath sweeping hems and tailored silhouettes, ensuring her proportions remain polished without visually overpowering her partner.

Kate Bosworth Embraces 1970s-Inspired Monochrome Style in New York City

Following her high-glamour appearance at the Oscars, Kate Bosworth shifted into a sophisticated monochrome moment while out in New York City on March 29, 2023. She was photographed leaving a taping of The Drew Barrymore Show as part of her press tour for the film Last Sentinel. The actress traded her structured red-carpet gown for a breezy, 1970s-inspired ensemble that leaned into a “clean girl” aesthetic with a bohemian twist.

The core of her look consisted of ivory-colored separates from the Zimmermann spring 2023 “Wonderland” collection. She wore the Wonderland waistcoat, a slim-fitting vest, paired with matching Wonderland tailored pants. The trousers were notable for their flared silhouette and a delicate gold chain detail that acted as a built-in belt at the waist.

To complete the outfit, Bosworth leaned into her long-standing relationship with the fashion house Chloé. She carried a Chloé Penelope small soft shoulder bag in a complementary tan shade and wore a pair of Chloé Daisy platform sandals, which have been a recurring staple in her wardrobe for several years.

Her beauty look for the day featured a voluminous, bouncy blowout, providing a soft contrast to the tailored lines of her waistcoat.
