When casual is executed with cool details, à la Bar Refaeli, the resulting look feels pulled-together, never sloppy. We're drawing inspiration from the model's airport style — a perfect mix of easy, seasonal pieces and smart accessories. We love how a pair of luxe, leather motorcycle boots and a quilted bag anchor her sweater coat for a more polished effect. On its own, a knit like this might feel oversized or undone, but slim black jeggings balance her proportions, and a pair of Ray-Ban shades provide the quintessential finishing touch.
