2. +J (Uniqlo x Jil Sander)
Year It First Dropped: 2009
Iconic minimalist designer Jil Sander made a name for herself with slim cuts and precise tailoring. Perhaps then, it isn't too surprising that when she decided to come out of retirement in the fashion world, it was to design for uber-minimalist retailer Uniqlo. Their restrained approach to clothing and branding fell in line with Sander's body of work, and the end result wasn't a diffusion collection at all—it felt more like an ambitious project meant to create the modern uniform for anyone. And really, that's what a legend like Jil Sander strived for.
