This past fall during the spring shows, style-setters on the streets of fashion capitals showed a renewed fondness for black-and-white patterns, particularly in form of polka dots. There were some graphic stripes and op-art effects, but mostly there were dots. The spots are appearing in Pre-Fall collections as well, a sure sign that they will move forward for Spring 19 and well as Fall deliveries. Bright bags or shoes are the perfect accents.
