The Dolce & Gabbana Feud: The Battle That Redefined Their Relationship

The most explosive and defining conflict between the sisters in recent years is the Dolce & Gabbana feud, which was the central storyline of The Kardashians Season 3. The core issue was Kim's decision to creative direct a Dolce & Gabbana fashion show in Milan, which Kourtney felt was a direct slight because the design duo had styled her own wedding to Travis Barker just months earlier in Portofino, Italy.

Kourtney expressed that Kim's collaboration felt like she was using her wedding as a "business opportunity" and stealing her "wedding country" aesthetic. This feeling of appropriation was so deep that Kourtney described Kim's move as the ultimate "revenge" after years of underlying sibling rivalry.

The Aftermath: Tension and the 'Not Kourtney' Group Chat

The fallout from the fashion collaboration was immediate and public. Kourtney felt blindsided and hurt, leading to a significant strain on her relationship with both Kim and Khloé Kardashian. The tension was so palpable that Kim even revealed the existence of a "Not Kourtney" group chat, further illustrating the divide within the family.

While the feud was never fully resolved on camera, the sisters appear to be maintaining a professional working relationship, a testament to the family's "business first" mentality. Kim made a public effort by tagging Kourtney in a social media post related to a Dolce & Gabbana dinner. More notably, the sisters recently collaborated on a SKIMS x Dolce & Gabbana campaign, suggesting a truce or at least a willingness to work together for their mutual financial benefit.

7 Shocking Ways The Kim vs. Kourtney Rivalry Fuels Their 2025 Empires

The ongoing rivalry, far from being a liability, has become a key driver for the sisters' individual brands, generating media attention and LSI keywords that dominate search results. Here are the most significant ways their tension is creating monumental success in 2025:

1. SKIMS vs. Lemme: The Billion-Dollar Wellness War

Kim's SKIMS, a $5 billion powerhouse, and Kourtney's Lemme, a rapidly growing wellness brand, represent a modern business rivalry. Kourtney's brand, which focuses on health and supplements, is positioned as the "natural" alternative to Kim's fashion and beauty empire, allowing each sister to capture a different consumer segment while simultaneously creating a compelling, marketable contrast.

2. The 'Kravis' Effect vs. The Mogul Narrative

Kourtney's highly publicized marriage to Travis Barker, dubbed "Kravis," has created a distinct, edgy brand identity centered on romance and wellness, which is a departure from the family's traditional focus. This counter-narrative allows Kim to double down on her "business mogul" persona, focusing on her legal studies and her massive SKIMS valuation, giving the public two very different, yet equally captivating, stories to follow.

3. The 'Not Kourtney' Group Chat and Family Dynamics

The revelation of the "Not Kourtney" group chat and the subsequent on-screen drama with Khloé Kardashian and Kris Jenner provides endless content for The Kardashians Season 7. The public's fascination with the internal workings of the family—who is on whose side—translates directly into record-breaking streaming numbers and sustained media coverage.

4. Controversial Hiring Decisions and PR Strategy

Kourtney's decision to hire Julia Fox, Kanye West's ex-girlfriend, for a Lemme ad campaign in 2025, was a calculated public relations move. This seemingly minor decision reignited the drama surrounding Kim's ex-husband and created a fresh wave of headlines, proving that Kourtney is willing to use the family's complex history to generate buzz for her business.

5. The Appropriation of Aesthetics and Brand Identity

The Dolce & Gabbana feud highlighted the sisters' differing views on brand ownership and aesthetic. Kourtney feels protective of her personal milestones, like her wedding, while Kim views all family events as potential business opportunities. This fundamental clash of values is the engine of their on-screen arguments, creating viral moments and feeding the narrative that Kim is the cutthroat businesswoman while Kourtney is the free-spirited older sister.

6. Addressing Old Rumors for New Attention

The long-standing, though refuted, rumor that Kim had hooked up with Travis Barker was brought back into the public discourse, which Kim has had to shut down. While baseless, these high-profile denials keep all parties—Kim, Kourtney, and Travis—in the news cycle, inadvertently boosting their relevance and search rankings.

7. The Perpetual Cycle of Reality TV Content

Ultimately, the rivalry is the lifeblood of their reality show. The audience tunes in to see the authentic, often painful, moments of a sisterly relationship under the intense pressure of fame and fortune. The drama between Kim and Kourtney is the most reliable source of conflict, guaranteeing that every new season of The Kardashians will have a compelling, high-stakes narrative to drive viewership and ensure the longevity of their brand for years to come.
