• Stars ditched bright premiere looks for a pared-back “Berlin Black” aesthetic at the Marty Supreme after party.
• Rosé, Rachel Sennott and Charli XCX led the monochrome charge with denim, leather and sheer details.
• Dakota and Elle Fanning, plus other guests, echoed the low-key, fashion-forward dress code at Chateau Marmont.
H2: After-Party Dress Code — “Berlin Black”
Timothée Chalamet’s Marty Supreme premiere may have served bright, Southern California color on the red carpet, but the film’s after party at the Chateau Marmont steered sharply in the opposite direction. Guests favored a more subdued, downtown-meets-Berlin aesthetic — a mostly black palette that emphasized texture, tailoring and cool, casual silhouettes.
H3: Rosé: Casual cool with a leather edge
Blackpink’s Rosé led the understated set in a cropped black baby tee paired with flared blue jeans that skimmed her shoes. She elevated the look with a leather trench coat draped over her shoulders, eyewear and tousled hair for an off-duty, chic vibe that balanced comfort and polish.
H3: Rachel Sennott: Y2K denim and sheer daring
Rachel Sennott — who co-stars in I Love LA and has ties to the film’s circle — opted for a distinctly mid-2000s denim moment. Her low-rise, light-wash flared jeans and a sheer long-sleeve top channeled early-noughties sexiness with modern restraint. The result felt bold without being ostentatious, fitting the after-party’s moody theme.
H3: Charli XCX and the all-black uniform
Pop star and rising on-screen presence Charli XCX embraced head-to-toe black with a leather coat, loose trousers and pointed stilettos. Her look reflected a cinematic sensibility she’s been cultivating as she moves deeper into film projects — restrained, dramatic and camera-ready.
H4: Sisters in sync — Elle and Dakota Fanning
Elle and Dakota Fanning also supported the Los Angeles screening. Elle favored an ankle-length black dress with a bateau neckline for classic minimalism. Dakota leaned into the evening’s tone with a black car coat layered over a bralette and burgundy pencil skirt, proving the dress code could be interpreted in many stylish ways.
H5: What this means for after-party fashion
The Marty Supreme after party showed how celebrities reinterpret an evening’s mood. Where premieres present polished statements, after parties allow for subversions: low-rise denim, sheer tops, leather trenches and an all-black uniform that reads both effortless and intentional. For magazine edit and street-style watchers, it’s a reminder that the coolest looks often prioritize mood and texture over logo-driven glamour.
The night at Chateau Marmont confirmed one thing: even in a sea of black, personal touches — a cropped tee, a daring sheer layer, a leather coat casually worn — make each celebrity’s look distinct. And Rachel Sennott’s Y2K-tinged denim proved that nostalgic silhouettes are still firmly in rotation.
