Six Celebrity Denim Formulas to Copy for Effortless Spring Style

Spring 2026 has delivered a denim moment that feels both refreshingly uncomplicated and quietly precise. The season's dominant mood, described by Who What Wear's own trend editors as "a move toward pieces that feel relaxed but still intentional, polished but never overdone," is less about buying into a single silhouette and more about learning how to build around the jeans already hanging in your wardrobe. Six celebrities have made that lesson concrete. Their formulas are specific enough to replicate and versatile enough to adapt, which is exactly what makes them worth studying.

Hailey Bieber: Car Coat + Bootcut Jeans + High-Vamp Pumps

No one accelerates a trend cycle quite like Hailey Bieber. At the 2026 Super Bowl, she turned up in a fuzzy coat layered over jeans, a real-world preview of the car coat formula that has since spread across street style feeds globally. The combination she's refined this spring pairs a structured car coat with low-rise bootcut jeans and high-vamp pumps, the latter being the shoe shape that adds a ladylike arch to what is otherwise a deeply relaxed silhouette. Her looks, including the high-vamp heel pairing specifically, gain traction through user recreations on social media at a scale few other celebrities match. The aesthetic currency she's operating in is confirmed at runway level too: Marie Claire noted that similar styles to her 2025-26 looks dominated Spring 2026 collections from Balenciaga, Ottolinger, and Celine. The formula works because the car coat does the heavy lifting; the bootcut and heel simply keep it grounded.

Rosie Huntington-Whiteley: Sporty Jacket + White Jeans + Tote Bag

Rosie Huntington-Whiteley has spent a decade proving that the sharpest outfit formula is often the most restrained one. Her spring approach does not deviate: a sporty jacket, white jeans, and a structured tote. Where other celebrities experiment with silhouette or color, Huntington-Whiteley disciplines herself to quality and proportion. The sporty jacket, something between a windbreaker and a performance-influenced blouson, gives the white denim its edge without tipping into casual territory. The tote anchors the whole thing in practicality. For the former Victoria's Secret Angel, this is less a trend pickup than a codification of everything her off-duty wardrobe has always stood for: elevated minimalism that photographs beautifully precisely because nothing is trying too hard.

Elsa Hosk: Collarless Jacket + Cigarette Jeans + Loafers

Elsa Hosk's formula is the one with the most runway endorsement behind it this season. Cigarette jeans, the silhouette she's working with here, were a common sight on the Spring 2026 runways according to Marie Claire, characterized by their slender profile and a straight cut that runs cleanly from knee to ankle. Paired with a collarless jacket, the look takes on a refined, slightly sculptural quality; the absence of a lapel creates a cleaner neckline that lets the trouser shape do the talking. Loafers complete the equation with characteristically Scandinavian pragmatism. Hosk, a Swedish model with a minimalist sensibility sharpened by years as a Victoria's Secret Angel, wears this kind of formula with the ease that comes from never overcomplicating a good silhouette. It is, arguably, the most replicable look on this list for anyone already committed to narrow-leg denim.

Laura Harrier: Trench Coat + Stovepipe Jeans + Pumps

Laura Harrier's contribution to this season's denim conversation is anchored in a satisfying comeback story. Stovepipe jeans, the closely fitted high-rise silhouette that flatters through its clean, leg-lengthening line, are identified by Marie Claire as "everywhere" for Spring 2026, and Harrier has been among the most visible champions of that return. Her formula pairs a sweeping black trench coat with leg-skimming stovepipe jeans in a mid-wash finish, tucking in a crisp white T-shirt and finishing with pointed-toe pumps that carry a sleek kitten heel. The proportions are the point: the drama of the long trench against the sharp, narrow denim creates a silhouette that reads immediately polished. Adding Prada sunglasses in the street-style version she's been photographed in recently signals that this is a woman who understands how much one considered accessory can shift the register of an otherwise simple outfit.

Jennifer Lopez: Blazer + Stripe Button-Down Shirt + Flare Jeans

Jennifer Lopez has never been a minimalist, and her spring denim formula reflects that. High-waist flare jeans form the base of a look that layers a striped button-down shirt under a blazer, bringing some of the era when wide-leg and flared silhouettes were the uncontested denim standard back into the present with considerably more sharpness. The stripe on the shirt does something important here: it introduces visual movement that connects the proportions of the blazer shoulder to the sweep of the flare hem, keeping what could read as a retro look firmly in the current moment. Wide-leg and flare styles are still ranking high in Spring 2026 trend reports, meaning Lopez's formula speaks to an audience that never quite gave up on volume below the knee and was simply waiting for the runway to agree with them again.

Bella Hadid: Stripe Sweater + Barrel-Leg Jeans + Embellished Belt

Bella Hadid's formula is the most directional on the list, and appropriately so given her position as one of fashion's most closely watched movers. Barrel-leg jeans, with their distinctive curved, wide-through-the-thigh shape that tapers slightly toward the ankle, represent the freshest silhouette in the spring 2026 denim field. Hadid pairs them with a stripe sweater, keeping the top half relaxed and pattern-driven while the barrel leg provides the structural statement. The embellished belt is the formula's defining gesture: it cinches the sweater into the waistband, defines the silhouette, and turns an accessory into the focal point of the whole look. Hadid's denim credibility this season is particularly strong; her Miss Sixty collaboration, unveiled at a Milan storefront appearance in February, confirmed her investment in the category as a creative participant rather than just a wearer.

The throughline connecting all six formulas is the same one that defines Spring 2026 denim at large: each look is built on a clear, uncomplicated pairing logic that makes the jeans feel like the starting point rather than an afterthought. Whether the silhouette is narrow, bootcut, flared, or barrel-shaped, the formula structure, outerwear or tailoring over denim, grounded by the right shoe and one considered accessory, remains consistent. The global denim jeans market, valued at USD 77.43 billion in 2025 and projected to surpass USD 125 billion by 2033, reflects just how commercially central this category is. But the six formulas above make the case that the most persuasive denim argument for spring is not about spending more; it is about pairing smarter.
