In 2025, the fashion industry is a buzz with one giant tale — Lululemon vs Costco. One is a high-end activewear brand. The other is a mainstream wholesale store. Now, they’re competing head-to-head in court over leggings.
Break it down in plain language: What’s the problem? Why does it matter? And how might this impact you as a consumer?
What’s the Lululemon vs Costco Scandal About?
Lululemon, the popular brand for high-end yoga pants and exercise wear, sued Costco. They accused Costco of selling leggings that are too similar to Lululemon’s Align line, but for significantly less money.
In brief:
- Lululemon alleges Costco leggings are knockoffs of their styles
- Costco sells them at discounted prices (approximately $20–$25)
- Lululemon leggings retail for about $98 per pair
- The suit alleges this would confuse consumers and damage Lululemon’s reputation
Why Is This Lawsuit a Big Deal?
It’s not about leggings — it’s about brand protection, fashion, and the law. Design copying is a big deal in the fashion industry, particularly when lower-priced versions come out quickly.
Big reasons this lawsuit is important:
- Brand reputation: Lululemon prides itself on high-end products and quality. Counterfeits could damage their reputation.
- Consumer trust: Customers might wonder whether they’re purchasing the authentic product.
- Retail trends: More individuals purchase imitations from inexpensive retailers such as Costco, Walmart, and Amazon.
- Legal questions: The case can potentially alter the level of protection fashion designs enjoy in the future.
What Lululemon Says
Based on legal filings, Lululemon charges that Costco is infringing on their trademark “Align” design — which is characterized by:
- A particular high-rise waistband
- Buttery-soft material
- Limited seams
- Signature shape and stitch
- Lululemon asserts that these elements are being utilized on Costco’s Kirkland leggings improperly, potentially deceiving consumers.
Costco’s Response
To date, Costco has not publicly replied at length. But overall, large retailers contend:
- Leggings are not unusual designs
- Less expensive products provide consumer option
- There’s no brand name employed, so it’s not an outright counterfeit
- It’s up to the court to determine if Costco violated any laws or if it’s merely fair competition.
What It Means for Shoppers in the U.S.
If you’re a shopper at one of those stores, here’s what it means for you
If You Love Lululemon:
- You might see more copycat items appearing
- This case could aid in preserving design originality
- Prices will most likely remain premium, particularly for special lines
If You Shop at Costco:
- You could see products in different availability
- Some leggings could be removed from store shelves
- Prices and fashions might change based on the outcome of the lawsuit
Are Knockoff Leggings That Bad?
Depends. Some consumers like cheaper versions, particularly when the economy is hard to swallow. But companies like Lululemon contend that imitation degrades the value of creativity and design effort.
Advantages of purchasing cheaper versions:
- Save money
- Same look and feel
- Easy to locate in the neighborhood store
Disadvantages:
- May not endure
- Could be supporting unethical duplication
- May confuse consumers regarding real vs fake
Can Fashion Designs Be Protected Through the Law?
That’s where it gets complicated. U.S. fashion laws are still not extensive, and it’s difficult to safeguard broad styles such as leggings or tank tops.
But if the design is distinctive enough, companies can sue under:
- Trade dress laws
- Trademark infringement
- Unfair competition
- That’s precisely what Lululemon is attempting to do here.
