This isn't the first time the athletic wear company has levied an accusation against a retailer selling supposed Lululemon dupes.

The Canadian athleisure brand has accused the warehouse club operator of copying at least six of its products, including its Scuba hoodie and men’s pants.

Lululemon filed a lawsuit Friday accusing Costco of copying its patented athleisure designs and selling them under its Kirkland Signature brand, according to NPR. The complaint alleges Costco is unlawfully trading on Lululemon’s reputation by offering unauthorized apparel at lower prices.
