Lululemon has filed a lawsuit against Costco, alleging that the retailer’s Kirkland Signature activewear copies its signature designs, including the Scuba hoodie, Define jacket, and ABC pants. Filed in a California federal court on June 27, 2025, the complaint claims the lookalike products infringe on Lululemon’s patents and trade dress, potentially misleading consumers. The lawsuit also names third-party brands like Danskin and Jockey. Lululemon seeks damages and a court order to halt sales and advertising of the disputed items. The case highlights growing tensions in fashion retail as “dupe culture” blurs the line between inspiration and imitation.
