It's just blue. Remember the scene from The Devil Wears Prada? There was hardly a designer that didn't have blue represented in a couple of fashions on the runway. See any Cerulean? The designers are Matthew Williamson, Karen Walker, Preen and Anna Sui. Each with a panache of it's own making.
Implications - New York Fashion Week is often revered as the mecca or holy grounds for fashionistas. What's seen on the runway during fashion week will dictate what is seen everywhere else for years afterward. Thus, those within the fashion publication, interior design or retail industries should keep up-to-date with the fashion industry in order to keep an eye on what's current.
