Karl Lagerfeld took a natural approach this season with a Fall 2012 collection inspired by minerals. Things were crystal clear on the runway, where models emerged from a crystalline set clad in geologically inspired confections. Playing with geometry and color, the designer delivered looks that were cubic and modern. Crystal embellishments and glistening sediment lent a sheen to a variety of prints and textures. And though he was influenced by the earth’s core, Lagerfeld’s creations remain out of the world.
