Adria Arjona Redefines the Little Black Dress in Calvin Klein at the Onslaught Premiere
Runway Magazine Editorial Team
Adria Arjona Calvin Klein styling just gave the classic black dress a genuinely modern edge. She brought the label’s deconstructed minimalism to her own movie premiere.
Adria Arjona wore a strapless black dress from Calvin Klein Collection’s Fall 2026 ready-to-wear line to the Los Angeles premiere of Onslaught, pairing the deconstructed design with Tiffany & Co. jewelry and boyfriend Jason Momoa by her side.
This look matters because it comes from the same collection that debuted at New York Fashion Week in February 2026. Furthermore, seeing it translated onto a red carpet shows exactly how Calvin Klein’s new creative direction reads in real life.
What Did Adria Arjona Wear to the Onslaught Premiere?
Arjona wore a slim-fitting, strapless black column dress featuring deconstructed detailing at the bodice. According to WWD, the asymmetric sweetheart neckline exposed a neutral taupe panel beneath folded black fabric, creating a peekaboo effect at the bust. Slight cinching at the waist further defined the dress’s slim silhouette.
The dress made its runway debut during New York Fashion Week in February under Veronica Leoni, who was named Calvin Klein Collection’s creative director in May 2024. Adria Arjona black dress styling here reflects Leoni’s broader approach to the collection, which pulled from the brand’s archives to blend sharp minimalism with pared-back, body-conscious tailoring.
How Did Arjona Accessorize the Look?
Arjona turned to Tiffany & Co. for her jewelry, wearing Apollo by Tiffany ear clips and a matching ring, both crafted in 18-karat gold and platinum with diamonds. The two pieces retail for a combined $116,500. As a Tiffany & Co. ambassador, Arjona previously starred in the jewelry house’s 2026 Valentine’s Day campaign, giving this pairing a natural brand connection.
Calvin Klein Collection 2026 styling emphasized restraint everywhere except the dress’s central detail, keeping hair and makeup similarly understated. That pared-back approach let the exposed corset panel serve as the look’s clear focal point rather than competing with additional statement accessories.
Who Joined Arjona at the Onslaught Premiere?
Jason Momoa accompanied Arjona on the red carpet, continuing their pattern of supporting each other at major premieres since going public with their relationship. Per W Magazine, the couple shared visible affection throughout the event, extending a dynamic they’ve maintained across previous red carpet appearances together.
Onslaught premiere fashion extended beyond just Arjona’s look, with co-stars Dan Stevens and Drew Starkey also walking the carpet at Regal L.A. Live. In the film, Arjona plays Celeste, a retired army sniper protecting her daughter from genetically engineered super soldiers. Onslaught opens in theaters, including IMAX screens, on September 4. Runway will track Arjona’s next red carpet appearance closely as her film promotion continues.
