Zoe Kravitz, 36, attended a New York City event Wednesday honoring jeweler Jessica McCormack, appearing without a companion as reports and public sightings have linked her in recent weeks with two high-profile entertainers.

Kravitz arrived at the cocktail reception held at The Frick Museum to mark McCormack’s Madison Avenue boutique opening wearing a sleek, black cocktail dress with lace accents and a high side slit. She wore her hair down and completed the look with high-heeled stilettos and evening makeup.

The appearance came amid heightened public attention on Kravitz’s personal life. She has been seen on multiple occasions with actor Austin Butler while promoting their new film, Caught Stealing. Separately, Kravitz was photographed holding hands with singer Harry Styles during a recent walk in New York City, and news reports said she introduced Styles to her father, musician Lenny Kravitz. Neither Kravitz nor representatives for the other parties commented at the event.

The reception drew a number of well-known attendees. Actress Shailene Woodley arrived in a white T-shirt paired with leopard-print trousers and was seen greeting Laura Dern, her Big Little Lies co-star. Dern wore a dark, lace-accented ensemble. Fashion figure Olivia Palermo opted for an all-black look, while Sabrina Dhowre, wife of actor Idris Elba, wore a patterned skirt over checked trousers.

McCormack, who has designed pieces for high-profile clients including Rihanna, attended the event in a simple black maxi dress. The jeweler’s boutique on Madison Avenue was the focus of the evening’s celebration, which combined a private reception with a view of the museum’s galleries.

Kravitz’s appearance at the event marked one of several public outings for the actress in recent weeks; she has balanced promotional duties for Caught Stealing with appearances on social and public engagements. The film promotions have been cited as the setting for on-camera interactions between Kravitz and Butler that fans and media characterized as notable chemistry.

The sightings with Styles prompted separate coverage after the pair were photographed together in Manhattan. Reports that Kravitz introduced Styles to her father were circulated in entertainment outlets; such introductions are commonly reported by sources close to public figures but were not independently confirmed at the event.

The Frick reception underscored the intersection of fashion, film and music that often accompanies New York social events in the fall calendar. Guests used the evening to view McCormack’s work and to mark the jeweler’s expansion to a permanent retail location on Madison Avenue.

Representatives for Kravitz, Butler, Styles and McCormack did not immediately respond to requests for comment. The actress is scheduled to continue promotional appearances for Caught Stealing in the coming weeks, while McCormack’s boutique is set to receive additional industry and media attention following the public event.
