Nike presents their new Spring 2015 Nike Air apparel collection just in next for the upcoming NBA All-Star game. Designed with layering and proportion in mind, the collection features stylishly elongated silhouettes designed to work together. Each element of the collection was designed together rather than independently, meaning you can and should wearing the short-sleeved hoodie over top the long-sleeved tee, or shorts on shorts. The collection employs what Nike designers call the Pivot System of Dress., which comprises four main pillars: length, layering, proportion and consistency. The lookbook features upcoming court stars, Ruby Gay, Anthony Davis and James Harden rocking pieces from the collection. Take a look through the new collections lookbook below.
