Hailey Bieber Has a '90s Moment in a Plunging Neon Corset Dress

After a short trip to Paris Fashion Week to promote her new clothing line with Wardrobe NYC and attend the Saint Laurent runway show, Hailey Bieber stepped out for the Barbara Berlanti Heroes Gala Benefiting F*ck Cancer in Santa Monica, CA on Oct. 1. The 25-year-old Tiffany & Co. brand ambassador made an electrifying statement in an Andreas Kronthaler for Vivienne Westwood neon corseted dress, which featured draped jersey fabric across the bodice and halter-style neckline.

So as not to take away from the vibrancy and dimension of the midi, sourced by stylist Dani Michelle, she opted for nude Giuseppe Zanotti Sophie sandals, playful diamond stud earrings in the shape of stars, and her engagement ring. Bieber's jet black manicure was a surprising twist, and her deep plum lip — courtesy of Leah Darcy — underscored the same mood. Hairstylist Irinel de León secured Bieber's brown hair back into a tightly wound bun with a center part, making for a '90s moment through and through.

Bieber's carousel post documenting the evening invited plenty of compliments from fellow celebrities and models, including Ashley Graham, Kylie Jenner, and Khloé Kardashian, who wrote, "Oh wowwwwwwwwwww lost my thoughts."

The outing comes after the release of Bieber's "Call Her Daddy" podcast with Alex Cooper, which addressed rumors about her relationship timeline with husband Justin and his own ties to Selena Gomez. Bieber also discussed her mental health during the hour-long episode that featured a video component.
