Hailey Bieber Brings Back ’90s Heat in Vintage Gucci Thong Dress at GQ Men of the Year Party

Hailey Bieber delivered a full dose of ’90s nostalgia at the 2025 GQ Men of the Year party, showing up in a look that instantly stopped the red carpet chatter. The model chose a sheer vintage Gucci gown that glimmered under the lights, styled with one of the label’s most iconic pieces from the Tom Ford years: a jeweled Gucci thong.

Her dress had a halter neckline and a long, easy silhouette that caught the light with every move. A high back slit added more drama, although most of the attention went to the open back that revealed the vintage thong, a piece once worn by stars like Kim Kardashian and Solange. With its sparkling Gucci emblem, the thong became a built-in accessory that tied the entire look together.

Hailey kept the rest of her styling simple and clean. She wore her blonde hair in a soft updo that felt effortless, letting the outfit take center stage. Her jewelry stayed timeless: diamond earrings, a classic tennis bracelet, and her standout wedding ring from Justin Bieber.

She was one of this month’s GQ cover stars and also served as a co-host of the Los Angeles event, joining Stephen Colbert, Seth Rogen, SZA, Oscar Isaac, Clipse, and Sydney Sweeney. This year marked the 30th anniversary of the GQ Men of the Year celebration, and Hailey’s outfit helped set the tone for a night built on style, personality, and a clear nod to fashion history.
