By now Olivier Theyskens knows how to strike the right balance between a cool, rock ’n’ roll vibe and an elegant refinement for his Theory collection. He kept resort light but with a hipster edge by mixing colors, prints and textures. “There’s a playfulness in mixing things up,” the designer said. Case in point, a sheer embroidered net dress worn over a printed top and denim shorts. There were also beautiful handcrocheted knits in multicolor yarns, sleek leather jackets, acid-washed jeans (hello, Eighties!) and colorful print dresses that all went well beyond those fashion basics.
