Wednesday night’s Tiffany & Co. party at Sunset Towers in West Hollywood was a glam, celebrity-studded affair that attracted a variety of fashion icons. The soiree provided a feast of fashion inspiration with appearances from celebrities like Hailey Bieber in a completely sheer black gown and Kim Kardashian in a monochromatic ensemble finished with a leather duster. Halsey and Lori Harvey also made an appearance.

Bieber arrived at the Tiffany & Co. event wearing a completely see-through Saint Laurent black dress, just days after posing for a photo with Selena Gomez inside the Academy Museum Gala earlier this month, which promptly caused all of social media to lose their cool. The matching black bra and briefs set, which could have been worn as a bikini, sat atop the ankle-grazing silhouette. She completed her daring look with a green pendant necklace, strappy black stilettos, layered bracelets, small hoop earrings, and small hoop earrings.

Halsey also wore an autumn-friendly brown leather ensemble from the Bronx and Banco spring 2023 collection on the red carpet. The just-off-the-runway outfit featured gold hardware and a striking cutout detail at the front. Harvey wore a white top, black pants, black heels, black tights, and simple silver bracelets for this event. Harvey had just debuted a custom purple ensemble created by Ibrahima Gueye at the Wearable Art Gala.
