Even after many decades in the apparel game, the German megabrand Adidas is still keeping things fresh — and not only through its signature sportswear line. In 2010, the company launched Adidas Originals Blue: a retro-inspired heritage collection of men's and women's track suits, hoodies, and other casual streetwear. Originals Blue draws from traditional Adidas looks (the name itself refers to the signature “bluebird” shade used in the Adidas Originals logo) to create jackets, Adicolor trainers, dyed leather high-top sneakers, and other beloved styles for the ultra-modern set. Fans of the brand's classic trefoil logo, take note: This is the only Adidas line where you'll find it. Fun fact: German businessman Adolf Dassler founded Adidas in 1948 after having a falling-out with his brother Rudolf, who went on to create another German sportswear label you've probably heard of — Puma.
