Alexandre Herchcovitch is hard to pin down, but lepidopterists would have a field day with his spring collection, which resembled rare, topical, multicolored insects caught in the middle of metamorphosis. There’s no telling how a dress got from one point to another. Often the front appeared to shed the back from the shoulders, like an iridescent cicada emerging from a shell of old skin. And just about everything pulled a tantrum of Technicolor ombré, while Herchcovitch’s collaboration with Mykita yielded four pairs of sunglasses inspired by the full-moon eyewear of Le Corbusier. Still, despite the zaps of electric color, the execution felt less like a near-death experience in a tanning bed than a pleasant bask in one of those sunshine light bulbs.
