Cheaper look-alikes have been around for years, but social media has made them more popular. Dupes can move into shaky legal territory if concerns arise around consumer confusion or patented designs.

Renowned apparel brand Lululemon has reportedly sued the popular membership-based warehouse club Costco. According to a People report, Lululemon filed a lawsuit in federal court in California on June 27, 2025. The legal dispute stems from Lululemon’s claim that Costco sold imitations of its signature apparel under the Kirkland brand.

This Costco product recently went viral (again), with fans on social media claiming it’s different. The price? Just $12.99. And while I may not be sold, I also can’t blame the shoppers who are. Because when something looks this close to a $94 best-seller for a fraction of the price—it makes even the most loyal Vuori girlie (myself included) think twice.
