For some, longer days and rising temperatures are a time to break out the brights. But at a slew of early summer fetes, the fashion flock proved a black-and-white palette can be a chic formula for hot-weather urban dressing. Fernanda Niven and Allison Sarofim looked to eyelet and broderie anglaise detailing, respectively, to punch up their monochromatic ensembles. Diane von Furstenberg, Jennifer Creel and Helena Christensen used metallic accessories in shades of silver and pale gold to add sparkle and shine. Others — perhaps taking a cue from the checkerboard floor of that ubiquitous Gramercy party spot — chose to mix black and white to stylish effect. Witness Tory Burch‘s sleek and slick pencil skirt combo. After all, not everyone has it as easy as the Olsens when it comes to choosing sides.
