Sydney Sweeney GQ party dress was the center of attention at the 2025 GQ Men of the Year party, which took place in Los Angeles on Thursday, November 13. The Euphoria star, known for her dramatic fashion evolution, chose a vintage 1995 Gianni Versace dress that showcased her figure and bold style on the red carpet.
Sweeney, 28, wore a striking black gown defined by its sculpted neckline and thick straps, perfectly highlighting her famous curves. The fitted bodice and classic column skirt contributed to a sophisticated yet daring silhouette, clearly echoing the style of a true Hollywood trendsetter. The party, held at a premiere Los Angeles venue, saw Sweeney effortlessly command the spotlight beside other major celebrities.
Makeup and Hairstyle Amplify Grunge Glamour
To elevate her look for the evening, Sweeney opted for a bold makeup style that added an edgy, grunge-inspired touch. Her bronzed cheeks and muted blush contributed to a glowy base. Meanwhile, she emphasized her blue eyes with black eyeliner lining her waterline and charcoal shadow blended expertly into her crease. Mascara and perfectly manicured brows completed the look, while light pink lips added softness.
Sweeney’s recently debuted blonde bob was styled into wet, beachy waves, parted to the side for a modern, chic vibe. To complete the outfit, she accessorized with a black choker, further reinforcing a punk-inspired aesthetic. This combination of daring fashion and strong beauty choices underscored her reputation for confidently experimenting with her style.
Recent Fashion High Points: Daring Sheer Looks and Big Hair Changes
Sweeney’s fashion risk-taking extends beyond the GQ party. At the Variety Power of Women event in October, she stunned in a sheer silver dress featuring a scoop neckline, short sleeves, and a fitted waist, which flowed into a pleated skirt, revealing her legs. Pieces like this have contributed to her growing status as an influential style icon.
To bring extra drama to her Variety Power of Women ensemble, Sweeney finished the look with diamond earrings and matching rings, echoing a taste for sparkle and luxury. Her bob on this occasion was styled in a smooth blowout with flirty flipped-up ends, complemented by soft eyeshadow, pink lips, and long lashes for a polished effect.
Transformative Hair Journey: The Bob Debut and Creative Team
Sweeney first revealed her chin-length bob in October at the Christy premiere during AFI Fest. The dramatic chop marked a turning point and made headlines for its bold contrast to her previously long, wavy hair. Glen Coco, the hairstylist behind the transformation, was credited for pushing creative boundaries and introducing a new look for the actress.
So my hairstylist Glen Coco just wanted to be able to do something different and I’m his little science experiment,
Sweeney quipped.
I love him so much [that] I let him cut and color my hair.
It was such a huge change! I was a little nervous,
Sweeney explained, recalling how her hair cascaded to her waist before the change.
I think my long hair became my security blanket,
Sweeney added.
I always wanted it down [and] wavy. But I’m loving this.
She described the transformation as meeting a new version of herself, saying:
In the mirror I’m like, “Ooh!’
Creative Collaborators Reflect on Sweeney’s Style and Hair Transformation
Jacob Schwartz, Sydney Sweeney’s colorist, also played a key role in her revamped appearance for recent red carpet events. Schwartz revealed that Sweeney was searching for a fresh change to go alongside her new film, Christy, and the timing of the transformation was deliberate.
[Sydney] wanted to have a big hair moment for the red carpet to support her new movie, Christy,
he recalled.
It felt like the perfect time to do something bold.
To achieve the updated look, Schwartz lightened Sweeney’s color from her signature dark suede blonde to a brighter tone, aiming to accentuate her eyes and features. He noted that the new shade “complements her cut so well,” matching the energetic and passionate spirit she conveyed on the red carpet.
In another notable appearance, Sweeney showcased her bob with a soft pastel pink Miu Miu dress. This ensemble featured a fitted bodice, halter neckline, and a full A-line skirt with lace details, which she paired with statement diamond jewelry for extra sophistication.
