Lululemon, a premium athleisure brand, is suing Costco, alleging the retailer sold “knockoff” versions of its popular ABC pants, Scuba hoodies, and Define jackets. Filed on June 27, 2025, in California federal court, the lawsuit claims Costco’s Kirkland 5 Pocket Performance Pant and other items infringe on Lululemon’s trade dress, confusing consumers and harming its reputation (). A viral YouTube video calls the lawsuit “a mess,” arguing Lululemon’s claims over design elements like gussets and back yokes are weak because they’re common in clothing (YouTube, July 3, 2025). This blog explores the Lululemon-Costco dispute, the trade dress argument, and what it means for consumers and businesses.

What Is the Lululemon vs. Costco Lawsuit About?
On June 27, 2025, Lululemon filed a 49-page lawsuit in the U.S. District Court for the Central District of California, accusing Costco of infringing its intellectual property (IP) by selling “confusingly similar” dupes of its Scuba hoodies, Define jackets, and ABC pants under brands like Kirkland, Danskin, Jockey, and Spyder (,). Key allegations include:
- Trade Dress Infringement: Lululemon claims Costco’s products mimic the “look and feel” of its patented designs, violating trade dress under the Lanham Act ().
- Consumer Confusion: Costco’s lower prices (e.g., Kirkland 5 Pocket Performance Pant at $10 vs. Lululemon’s $128 ABC Pant) allegedly trick customers into thinking they’re buying Lululemon products or that Costco’s items are made by Lululemon (,).
- Specific Products: The lawsuit highlights six items, including Costco’s Danskin Half-Zip Pullover ($8) vs. Lululemon’s Scuba hoodie ($118), and Spyder Women’s Yoga Jacket ($22) vs. Lululemon’s Define jacket ($128) (,).
- Tidewater Teal Color: Lululemon alleges Costco copied its trademarked color, though no Costco products in this color appear online (,).
Lululemon seeks damages for lost profits, an injunction to stop Costco’s sales, and removal of marketing materials (). Costco has 21 days to respond but hasn’t commented publicly ().
Why Is Lululemon’s Trade Dress Claim Controversial?
The YouTube video argues Lululemon’s trade dress claims are shaky because the design elements—like the ABC pant’s gusset, back yoke, and pocket rivets—are functional and common in clothing, not unique to Lululemon (YouTube, July 3, 2025). Let’s break down the claims:
- Gusseted Crotch: Lululemon’s ABC pant (Anti-Ball Crushing) features a diamond-shaped gusset for comfort and mobility. The lawsuit calls it “ornamental,” but the video notes gussets are functional, appearing in jeans like Levi’s 505 from 1967 ().
- Back Yoke: Lululemon claims the back yoke (a seam above the rear pockets) is decorative, but the video argues it’s a standard pattern-making feature to fit curved glutes, seen in decades-old designs (YouTube, July 3, 2025).
- Pocket Rivets: Lululemon calls the metal rivets on pockets “decorative,” but the video counters they reinforce pockets, a feature in most five-pocket pants ().
- Fabric and Stretch: Lululemon describes its ABC pant fabric as having a “synthetic, flat, semi-matte appearance” with “four-direction stretch.” The video highlights that Costco’s Kirkland pant lacks stretch, undermining Lululemon’s claim of similarity (YouTube, July 3, 2025).
The video suggests Lululemon’s claims may fail in court because trade dress must be non-functional and distinctive, per U.S. trademark law. Functional elements (e.g., gussets for comfort) aren’t protectable, and similar designs exist in brands like H&M and Tommy Hilfiger, which Lululemon admits don’t infringe ().
Legal Context: Trade Dress and U.S. Law
Trade dress protects a product’s distinctive “look and feel” that identifies its brand, like Nike’s Air Force One sneaker (YouTube, July 3, 2025). To win, Lululemon must prove:
- Distinctiveness: The ABC pant’s design is uniquely associated with Lululemon.
- Non-Functionality: The design elements (e.g., gusset, yoke) aren’t essential to the product’s function.
- Consumer Confusion: Costco’s products mislead customers into thinking they’re Lululemon’s ().
U.S. trademark law is “lax” compared to Europe, making trade dress cases tough to win (). The video notes Lululemon’s jury trial request may aim to sway non-expert jurors, as judges are stricter on legal wording (YouTube, July 3, 2025). X posts echo skepticism, with @Vmaxpax (June 29, 2025) arguing there’s “no IP protection on designs” like cuts or colors ().
Lululemon’s History of IP Lawsuits
Lululemon has a track record of defending its IP:
- Peloton (2021): Lululemon sued Peloton for copying its Align leggings, settling in September 2022 ().
- Calvin Klein (2012): Lululemon sued over Astro yoga pants’ waistband design but withdrew after a confidential settlement ().
- Cease-and-Desist Letters: Lululemon sent Costco a letter in November 2024, leading to some product removals, but claims Costco continued selling others (,).
This history shows Lululemon’s aggressive stance, but the video argues the current lawsuit overreaches by claiming common design elements (YouTube, July 3, 2025).
Consumer and Business Impact
The lawsuit has sparked debate, especially on social media:
- Consumers: The “#LululemonDupes” hashtag on TikTok highlights the popularity of affordable alternatives, with Costco’s $10–$22 items appealing to budget-conscious shoppers (,). However, some Reddit users note Costco’s Kirkland pants lack Lululemon’s quality and stretch ().
- Retailers: Costco’s stock hasn’t been affected, but a loss could force it to stop selling the disputed items, impacting its Kirkland brand (). Some X users, like @VeeCeeMurphy76 (July 3, 2025), argue the lawsuit may backfire by advertising Costco’s cheaper options ().
- Lululemon: The brand’s shares are down 37% in 2025 amid a “dynamic macroenvironment” and rising competition from Vuori and Alo (). The video suggests the lawsuit is a reaction to poor sales, a tactic seen in Nike’s 2023 Skechers lawsuit (YouTube, July 3, 2025).
Why the Lawsuit May Be a “Mess”
The YouTube video calls the lawsuit “a mess” because:
- Weak Claims: Functional elements like gussets and yokes are standard in clothing, not unique to Lululemon (YouTube, July 3, 2025).
- Market Mismatch: Lululemon’s premium customers differ from Costco’s budget shoppers, reducing confusion claims ().
- Publicity Risk: The lawsuit draws attention to Costco’s $10 pants, potentially boosting their sales, as noted on X (@Vmaxpax, June 29, 2025) ().
- Legal Hurdles: U.S. trademark law rarely protects clothing designs unless highly distinctive, and Lululemon’s cherry-picked non-infringing examples (e.g., H&M) weaken its case ().
If Lululemon wins, it could set a precedent for broader trade dress protections, impacting budget retailers. A loss could embolden dupe culture, already thriving on TikTok ().
What Can Consumers Do?
If you’re affected by this dispute or similar IP issues:
