Conjure pinup glamour of the '50s with Norma Kamali's Bill dress. Crafted from the label's signature slinky jersey in a monochromatic leopard print, the design has a sweetheart neckline with a halter strap that can be worn multiple ways, as well as ruching along the sides that creates a figure-hugging silhouette. Wear yours with barely-there sandals and an embellished clutch for a bombshell Saturday-night ensemble.
