Alexandre Vauthier's high-octane approach to eveningwear embraces dramatic cutouts and voluminous shapes, both of which are seen in this black blouse. Made in France, it's shaped from satin-backed crepe with long balloon sleeves that are slit open from the shoulder, then anchored with slender cuffs. Tuck it into a sequinned mini skirt and add stiletto heels for an evening occasion.
