Once dismissed as a fashion faux pas, double denim has undergone a renaissance, emerging as one of the season’s most sophisticated trends. The key? A refined approach that balances nonchalance with polish, as exemplified by Julianne Moore’s recent appearance in a head-to-toe denim ensemble.
At an event celebrating her capsule collection with Californian label Frank and Eileen, Moore demonstrated how to master the jean-on-jean aesthetic with effortless elegance. Her mid-blue, single-breasted blazer—cut in a relaxed silhouette—was paired with wide-leg jeans in the same wash, creating a harmonious yet understated look. Elevated with chunky gold jewelry and radiant makeup, the outfit struck the perfect balance between relaxed and refined, proving that double denim can be a chic evening option for the over-40 set.
The Evolution of Double Denim: From Taboo to Tailored
“Double denim has shed its once-taboo reputation,” notes stylist Nadia Phillips, who championed the trend at London Fashion Week in The Frankie Shop’s cropped indigo jacket and matching wide-leg jeans. “When executed with intention—through contrasting accessories or deliberate proportions—it exudes an insouciant cool.”
According to WGSN’s SS25 Trend Report, denim tailoring is poised to dominate, with wide-leg styles maintaining their stronghold (accounting for 27.1% of the market). Stylist and retail consultant Felicity Bird observes, “I’ve seen full denim looks transition seamlessly from boardrooms to dinners—the secret lies in sharp styling. Think structured loafers, minimalist gold hardware, and crisp layering with a silk camisole or white shirt.”
Runway Inspiration: Denim as Elevated Eveningwear
For skeptics, the Spring/Summer and Fall/Winter 2025 runways offer compelling arguments. Ralph Lauren reimagined denim as polished office attire with pleat-front palazzo pants and a matching blazer, while Tory Burch and Ulla Johnson presented ultra-refined indigo suiting with evening-ready allure.
“Designers are redefining denim’s casual DNA through architectural tailoring and luxe finishes,” says Phillips. “Bottega Veneta and Saint Laurent have introduced sleek, dark-wash suits that rival traditional suiting, while Brunello Cucinelli layers denim blazers over cashmere turtlenecks for understated sophistication.”
From Luxury to High Street: The Best Denim Suiting Options
The trend isn’t confined to luxury labels. High-street brands like Cos, Sézane, Paige, Levi’s, and Me+Em have delivered accessible iterations this season. Me+Em’s “Wear With Everything Blazer” epitomizes the versatility of denim suiting—pieces designed to be mixed, matched, and maximized.
Stylist Tips for Mastering the Denim Suit:
- Fabric & Fit: Opt for minimal stretch, structured cuts in a uniform wash.
- Luxe Pairings: Elevate with silk, suede, or polished leather accents.
- Accessorize Strategically: A slim belt (skip the rodeo buckles) or statement jewelry sharpens the look.
Styling the Denim Suit for Every Occasion
Daytime Ease
Florrie Thomas of Wrapp10 recommends leaning into the ‘70s vibe with a ruffled white blouse and tan accessories (Sézane’s Christie jacket and flares nail this aesthetic). Phillips and Bird suggest a white tee, vintage-wash straight-leg jeans, and ballet flats or sneakers for a more relaxed take.
Office-Appropriate Polish
Seek sharp lapels and defined shoulders (Simkhai and Paige offer flattering cinched-waist options). “Layer with a fine-gauge knit, pointed-toe loafers, and a streamlined tote,” advises Bird.
Evening Glamour
“Indigo denim feels inherently dressier,” says Thomas. “Pair with a tuxedo shirt, crystal embellishments, and a bold lip for after-dark appeal.” For a modern twist, Phillips suggests an oversized blazer with shoulder pads, black trousers, and stiletto heels for a monochromatic moment.
The Final Word
Double denim is no longer a sartorial gamble but a testament to thoughtful styling. Whether channeling Moore’s evening elegance or embracing runway-inspired tailoring, the modern denim suit is a wardrobe workhorse—proving that, when done right, jean-on-jean is the ultimate power play.
