Lululemon has filed a lawsuit against Costco, accusing the megaretailer of selling “dupes” of its popular athletic wear that were so similar they may cause “confusion, mistake, and deception”

Lululemon accuses Costco of making duplicates of several products, including its popular Scuba hoodies, Define jackets and ABC pants. Lululemon says one of the duplicates that Costco sells is the Hi-Tec Men’s Scuba Full Zip, with the lawsuit showing a screenshot image of Costco’s website showing the item priced at $19.97.

Zip Pullover purchased from Costco will set you back about $8. In a lawsuit, Lululemon Athletica alleged that the Danskin pullover and other products sold at Costco are illegal knockoffs of Lululemon’s premium activewear.
