In a fiery escalation of their sibling rivalry, Kim Kardashian has publicly called out her older sister, Kourtney Kardashian, accusing her of blatantly copying her iconic style. The explosive claim, made during a candid interview this week, has reignited tensions within the Kardashian clan, with Kim delivering a biting remark: “She has no idea how this works.” The accusation has sent shockwaves through their massive fanbase, sparking debates about originality, influence, and the blurred lines of fashion within one of America’s most famous families.

Kim, 44, has long been hailed as a trendsetter, her bold fashion choices—from figure-hugging Balenciaga outfits to avant-garde Met Gala looks—defining pop culture for over a decade. Kourtney, 45, has carved her own niche with a bohemian-chic aesthetic tied to her Poosh lifestyle brand and her romance with rocker Travis Barker. But according to Kim, Kourtney’s recent wardrobe evolution—think sleek leather ensembles and daring cutouts—bears an uncanny resemblance to her own signature vibe. “I’ve spent years building my look, working with designers, taking risks,” Kim vented. “She just swoops in and copies it like it’s nothing.”

The feud erupted after Kourtney was spotted at a Los Angeles event wearing a skintight black catsuit eerily similar to one Kim wore during Paris Fashion Week last year. Sources close to the family say Kim confronted Kourtney privately, only to be met with defiance. “Kourtney laughed it off and said fashion’s fair game,” an insider revealed. “That’s when Kim lost it—she feels like Kourtney’s piggybacking on her hard-earned status.” Kim’s “she has no idea how this works” jab seems to imply that Kourtney lacks the vision or industry savvy to craft an authentic personal brand, a dig that cuts deep given their competitive history.

Fans are divided. Social media lit up with side-by-side photos of the sisters’ outfits, with some accusing Kourtney of “stealing Kim’s playbook,” while others argue that fashion trends are universal and Kim doesn’t own the rights to sexy, minimalist looks. “They’re sisters! They’ve always shared clothes and vibes,” one supporter tweeted. Yet Kim’s camp insists this isn’t about inspiration—it’s about imitation without credit. “Kim’s not mad about borrowing; she’s mad Kourtney acts like it’s all her idea,” a friend explained.

This isn’t the first time the sisters have clashed. From business disputes over SKIMS and Poosh to onscreen spats during Keeping Up With the Kardashians, their relationship has weathered plenty of storms. But this style showdown feels personal, striking at Kim’s core identity as a fashion pioneer. Kourtney, meanwhile, has stayed silent, though her Instagram Stories—featuring more edgy outfits—suggest she’s unbothered by the accusations.

As the drama unfolds, the Kardashian empire thrives on the attention. Whether Kourtney’s channeling Kim intentionally or simply evolving alongside her, the feud has everyone talking—and shopping. Fashion sites are already reporting spikes in searches for “Kim-inspired catsuits” and “Kourtney’s leather looks.” Love or hate the rivalry, one thing’s clear: when these sisters square off, the world watches, and the cash registers keep ringing.
