For Spring/Summer 2013 Adidas continue to collaborate with Manhattan-based fashion house and luxury retailer Opening Ceremony, this time creating a series of pieces inspired by running and tennis, infused with nostalgic elements of 90's street fashion. The Patchwork Stitch Crew Sweater is an eccentric, mish-mash version of a classic tennis sweater, brought to life with a selection of patterns straight out of the 90’s.
