Adidas Originals is a subdivision of adidas dedicated to lifestyle, fashion, and heritage products. It is home to many brands' collaborations with fashion designers, celebrities, and cultural figures. For example, Pharrell's collaborations come under the adidas Originals by Pharrell Williams label (sometimes stylized adidas Originals = Pharrell Williams). Alexander Wang's products are adidas Originals by Alexander Wang, and so on. Adidas Originals is represented by the old-school Trefoil logo, which was replaced as the symbol of the brand's performance sportswear products by the "three bars" logo, introduced with the 1991's Equipment (EQT) line.
