In November 2015, COS launched a pop-up store in Downtown Los Angeles, created in collaboration with Daniel Arsham and Alex Mustonen of Snarkitecture. Located within Austere, a space for Scandinavian design, the week-long monochromatic pop-up transformed the industrial space. Visitors found themselves in a reflected world with a floor-to-ceiling mirror dissecting the room and the two near identical halves completely monochromatic. To celebrate this launch, on the evening prior to opening, the brand hosted a dinner within the iconic Bradbury Building for friends of the brand as well as local media and VIP’s.
