The collab: Jil Sander for Uniqlo
When: 2009-2011
Why: Before she announced her return to her eponymous line this year (much to everyone, including Raf Simons’ surprise) Jil Sander collaborated with Japanese retailer Uniqlo starting in 2009 on a line simply called +J. Fashion lovers went absolutely bonkers for the line, especially its outerwear. +J shuttered in 2011, leaving many of us to wonder where our winter coats will come from.
