Hailey Bieber delivered a full dose of ’90s glamour at the 2025 GQ Men of the Year party when she stepped onto the red carpet in a shimmering vintage Gucci dress. The sheer halter-style gown featured sparkling details, a daring back slit, and a dramatic open-back design that immediately turned heads.

Adding to the retro look, Hailey layered the gown with a vintage Gucci by Tom Ford thong — a bold fashion piece previously worn by icons like Kim Kardashian and Solange. The thong included jeweled Gucci accents that matched the gown’s glittering finish. Keeping her beauty look effortless, the Rhode founder wore her blond hair in a relaxed updo.
