The retail world is buzzing with the unfolding Lululemon Costco lawsuit, as the premium athleisure brand takes aim at the warehouse giant for allegedly selling “knockoffs” of its popular apparel. This high-stakes legal battle, filed on Friday, June 27, 2025, in a California federal court, has ignited discussions across social media, from TikTok dupe hauls to Reddit threads debating intellectual property. Lululemon, known for its iconic Scuba hoodies, Define jackets, and ABC pants, claims Costco is infringing on its trademarks and design patents by offering “confusingly similar” versions under its Kirkland Signature label and through other brands like Danskin, Jockey, and Spyder. This move by Lululemon signals a firm stance against the pervasive “dupe culture” that has reshaped consumer spending habits.
Lululemon’s complaint states that Costco has “unlawfully traded upon Plaintiffs’ reputation, goodwill and sweat equity.” The company argues these alleged dupes could mislead consumers into believing they are buying authentic Lululemon products or that some official connection exists between the two companies. Online platforms regularly feature videos comparing Lululemon items to their significantly cheaper Costco counterparts. For instance, a Lululemon Scuba hoodie can cost around $118, while a similar Costco item might retail for as low as $8. This price disparity highlights the economic implications at the core of the Lululemon Costco lawsuit.
Unpacking the Lululemon Costco Lawsuit: Claims of Infringement
The Lululemon Costco lawsuit centers squarely on intellectual property rights. Lululemon asserts that its designs, including unique construction techniques and “strategic fits,” are protected by law. The lawsuit specifically names several Costco products, claiming they mimic Lululemon’s design elements, fabric choices, seam shapes, and even specific color names, such as “Tidewater Teal,” which Lululemon claims to have used exclusively since 2019. Before initiating legal proceedings, Lululemon reportedly sent cease and desist letters to Costco, seeking an amicable resolution. With those attempts seemingly unsuccessful, Lululemon is now pushing for a jury trial.
Lululemon seeks not only to halt the manufacturing and sale of these disputed items but also to recoup monetary damages for lost profits. The company contends that Costco is unfairly capitalizing on Lululemon’s established brand reputation and product demand without making comparable investments in original research, development, and design. This legal challenge could establish a significant precedent for how the retail industry handles imitations and private-label products in the future, particularly concerning the increasingly popular “dupe culture.”

The Broader Implications for “Dupe Culture”
The Lululemon Costco lawsuit arrives amidst a booming “dupe culture,” largely fueled by social media, where consumers actively seek out affordable alternatives to high-priced fashion. While some argue that “dupes” democratize fashion by making trends more accessible, brands like Lululemon argue that direct copying constitutes intellectual property theft. The lawsuit cites articles from respected publications like The Washington Post and The New York Times, which have highlighted the striking similarities between Lululemon’s products and Costco’s more budget-friendly offerings, often noting a difference in material quality.
This legal action underscores the inherent tension between consumer demand for affordable lookalikes and a brand’s right to protect its original designs and substantial investments. For Lululemon, a brand built on premium pricing and strong customer loyalty, the widespread availability of these “knockoffs” directly threatens its market position and carefully cultivated image of exclusivity. The Lululemon Costco lawsuit sends a clear message: Lululemon is committed to vigorously defending its intellectual property and preventing unauthorized exploitation of its brand equity.
The Road Ahead in the Lululemon Costco Lawsuit
As of late June 2025, Costco has not yet formally responded to the Lululemon Costco lawsuit. Known for its dominant private-label brand, Kirkland Signature, Costco has faced accusations of selling “dupes” previously. However, this case brings a globally recognized brand like Lululemon directly into legal contention. The litigation process will likely involve a discovery phase where both parties exchange evidence and information. Lululemon’s request for a jury trial indicates a desire for public examination of design patents, trade dress, and how consumer perception is affected.
The outcome of this Lululemon Costco lawsuit could profoundly impact the landscape of private-label branding and the burgeoning “dupe” market. Should Lululemon prevail, it might encourage other high-end brands to pursue legal action against retailers offering similar, less expensive versions of their products. Conversely, if Costco successfully defends its position, it could signal a broader tolerance for design similarities within the retail sector, especially when products are sold under distinctly different brand names. Regardless of the final verdict, this case will undoubtedly spark ongoing debate about intellectual property rights in the dynamic fashion and retail industries.
