Light and shade, the key inspirations of Spring '15 for brother-and-sister team Marc Freeman and Camilla Freeman Topper, are pretty big ideas. So perhaps it's little surprise that they've turned out such a stark offering, using broad strokes to interpret those notions. Clean lines were the order of the day, with a few concessions made to watery, draped satin used on skirts and maxi dresses. Those looked particularly pretty juxtaposed with extra sharp outerwear, like one standout coat in a custom geometric jacquard, or another cocoon-like topper in glossy black-and-navy-checked raffia. Generally speaking, there was plenty of sex appeal here, but always tastefully tempered—thigh-high slits, say, came alongside mock-necks or double-breasted blazers; a jumpsuit's plunging neckline was juxtaposed with long sleeves and a looser silhouette. All these pieces had a certain power to them. Spring for Camilla and Marc may be spare—in places, perhaps a touch overly so—but certainly not without its charms.
