Cardi B's $40 Cardigans Nail Summer's Biggest Color-Combination Trend
Our take

The resurgence of accessible style moments, particularly those championed by figures like Cardi B, continues to reshape the landscape of fashion consumption. Her recent Old Navy campaign, initially celebrated for its denim offerings Cardi B x Old Navy Jeans Are Back in Stock, and I'm Getting Another Pair, has now broadened to include a surprisingly impactful detail: $40 cardigans embodying this season’s trending color combination of tomato red and blue. This isn't merely a fleeting trend; it's a reflection of a broader shift where high-fashion aesthetics are democratized and adopted by mainstream audiences through affordable, readily available pieces. The rapid sell-out potential, mirroring the frenzy surrounding her jeans, underscores the power of celebrity endorsement and the appeal of attainable luxury – a concept we’ve explored previously in our "Smart Shopper Edit" featuring pieces that offer elevated style without the exorbitant price tag The Smart Shopper Edit: 20+ Under-$350 Pieces That Look More Expensive Than They Are.
The current fascination with this particular red and blue pairing feels intrinsically tied to the runways, where similar palettes have been meticulously curated by luxury brands. It’s a testament to how trends, once confined to exclusive circles, are now rapidly disseminated through social media and celebrity styling, creating a feedback loop where high fashion informs accessible fashion, and vice versa. This phenomenon highlights the evolving role of the consumer – no longer solely dictated by top-down trends, but actively participating in shaping and accelerating them. The fact that Cardi B’s endorsement is driving this accessible interpretation of a runway trend isn’t accidental; it's a deliberate strategy leveraging her influence to create immediate and widespread impact. We've also seen this effect with other celebrities elevating more understated items, like Camila Cabello’s unexpectedly popular Adidas sneakers Sorry, Sambas—Camila Cabello's New Adidas Sneakers Are On Sale and So Overlooked, proving that the power of a well-placed endorsement can significantly impact sales and shift consumer preferences.
Beyond the immediate sales figures, this trend speaks to a larger cultural narrative about value and aspiration. Consumers are increasingly discerning, seeking pieces that offer both style and substance without sacrificing affordability. They are drawn to authenticity and relatability, which explains why someone like Cardi B, known for her unapologetic self-expression and down-to-earth personality, resonates so strongly. The $40 cardigan, therefore, represents more than just a seasonal color combination; it embodies a desire for elevated style within a realistic budget, a desire amplified by the visibility and influence of cultural icons. It’s a rejection of overt displays of wealth in favor of a more nuanced, intentional approach to personal style. This aligns perfectly with a growing appreciation for quiet luxury – an aesthetic that prioritizes quality, craftsmanship, and timelessness over fleeting trends and ostentatious branding.
Looking ahead, it will be interesting to observe how brands continue to navigate this democratization of fashion. Will we see more collaborations with celebrities who champion accessible style? Will the focus on runway-inspired color combinations persist, or will new trends emerge from unexpected corners of the fashion landscape? The rapid adoption and evolution of trends driven by social media and celebrity influence suggest a future where fashion is increasingly fluid, responsive, and ultimately, shaped by the collective desires of the consumer. The question remains: how will brands maintain exclusivity and brand identity in a world where high fashion aesthetics are so readily available and widely adopted?
Denim was the star of Cardi B's new Old Navy campaign, but the runway-ready color combinations featured deserve some applause, too. After wearing a tomato red top with the indigo jeans in the "Most Wanted Denim" ad, Cardi endorsed the cerulean blue and yellow color trends at the launch party in New York City.
Hours before Old Navy restocked the sold-out, very good Curvy Extra High-Waisted Cuffed Wide-Leg Jeans she wore in the commercial, Cardi joined chief creative officer Zac Posen at Manhattan's Ripple Room to celebrate. All eyes were on the campaign star, dressed in colorful knitwear, denim capri pants, and the celebrity-beloved Chanel 25 Bag (in another bold, grass green hue).

Cardi took style cues from her on-screen self by wearing not one, but two cardigans. The first sweater was a "Bodak Yellow"-approved shade of lemon. Seemingly inspired by the primary color-blocking trend that appeared on the spring 2026 runways, Cardi B didn't stop at one eye-squintingly bright hue. She topped the yellow knit with a cobalt blue one.
Celine, Jil Sander, Dries Van Noten, McQueen, Nina Ricci, and Loewe splattered blue-and-yellow looks all over the season's runways. Designers played with contrasting pops of blueberry and butter, highlighter yellow and cobalt, and even aquamarine and mustard. But be warned: With such a vast shade range, it's easy to overcomplicate primary colors. Take it from Cardi B: The contrasting combination looks best with everyday basics.



Cardi B's launch party picks are perfect for minimalists looking to test brighter color palettes. If her cardigans are anything like her Old Navy jeans, though, they won't stick around for long. When the $40 knitwear inevitably sells out, prepare yourself for sweater weather by shopping the Cardi-coded styles below.
