The sounds of spring, with babbling brooks and birdsong, set a serene yet surreal tone Wednesday as Elie Saab unveiled his latest couture collection inside the soaring Palais de Tokyo in Paris. It was punctuated only by whoops and clicking camera shutters as Eva Longoria swept in.

While the setting evoked pastoral bliss, the collection was a study in high-drama couture, as Saab's signature opulence met a new architectural precision.
