Most of us have probably seen a social media post or two hyping up a so-called “dupe” of a high-end product—whether it’s skincare, handbags, or in this case, athleisure. But there’s a fine line between affordable alternatives and outright intellectual theft. And in the case of Lululemon vs. Costco, that line seems to have been crossed.
On June 27, Vancouver-based Lululemon filed a lawsuit in California, accusing Costco of infringing on its patents, trademarks, and design rights. At the heart of this legal battle are products like Lululemon’s SCUBA hoodies, Define jackets, and ABC pants—all of which the company says have been copied by Costco under its Kirkland label or through partner brands. It’s not just about design similarities either. Lululemon claims that Costco even used trademarked color names like “Tidewater Teal” and product descriptors like “Scuba” to market its own apparel.
To the average shopper, these might seem like small details. But in the fashion world, and especially in the fiercely competitive athleisure market, these elements represent years of research, development, and brand-building. They’re not just colors or product names—they’re intellectual property, and they’re central to Lululemon’s identity as a premium brand.
Now, let’s be clear: competition is healthy and even necessary in a free market. It pushes innovation, brings prices down, and gives consumers choices. But there’s a big difference between competing and copying. Lululemon even acknowledges in its lawsuit that other brands like H&M and Tommy Hilfiger make similar products without violating intellectual property laws. So why is Costco being called out? Because according to Lululemon, this isn’t competition—it’s imitation disguised as value.
In a world where viral TikTok videos and Instagram reels drive consumer demand for “dupes,” retailers like Costco may be tempted to capitalize on trending products without going through the effort to create something original. But here’s the problem: if companies like Costco are allowed to mimic designs and marketing language this closely, it sets a dangerous precedent. It tells other businesses, especially smaller startups or designers, that their creativity and innovation can be copied with little consequence—as long as the price is right.
Lululemon has built its reputation on thoughtful design, quality materials, and a distinct aesthetic. These are not knock-off garments being sold on an obscure website—Costco is one of the largest retailers in North America. If they’re indeed selling lookalike apparel using similar names and styles, the damage to Lululemon’s brand equity is real. Worse, it undermines consumer trust. Imagine buying what you believe is a Lululemon-quality product, only to discover it falls far short.
Some of the products mentioned in the lawsuit, like Costco’s “Hi-Tec Men’s Scuba Full-Zip” or Spyder-branded jackets that echo Lululemon’s Define line, seem intentionally named and designed to blur the line for consumers. Whether that’s clever marketing or a legal liability is exactly what the courts will decide—but the optics certainly don’t favor Costco.
As of now, Costco hasn’t responded publicly to the lawsuit, and many of the items in question have quietly disappeared from its website. That move alone suggests a certain level of acknowledgment, if not guilt. And while silence isn’t an admission of wrongdoing, it doesn’t instill confidence either.
In the end, this case is about more than just yoga pants or zip-up hoodies. It’s about setting boundaries in a world that increasingly values trends over trademarks. Lululemon’s decision to sue is not just a defense of their brand—it’s a stand for any company that dares to invest in originality.
Because if we don’t protect true innovation, we’re only encouraging more imitation.
