RUNWAY: Versus Versace SS15New York Fashion Week has become the unofficial home of diffusion lines and collaborative capsule collections. When H&M has a new designer collaboration, they show it during NYFW. If a designer debuts a new diffusion line, they show it during NYFW. Italy's Versace does both this season. Donatella Versace tapped Anthony Vaccarello to design Versace's diffusion line, called Versus. The result was a black and white collection rooted in Versace's uber-sexy heritage. There were cut out tees, leather pants, glossy boots, covetable hightops and plenty of attitude.
