Natalie is a Bloomingdales salesgirl mooning over her ex-boyfriend; Felicia has been quietly in love with her boss for seventeen years; and Andie is a cynical private detective who specializes in cheating husbands. For these three women, as well as many others--a young model fresh from Alabama, a Hollywood star making her Broadway debut, an unemployed Brown grad whos been faking a fabulous life on social media--everything is about to change . . . and all thanks to the power of one perfect little black dress.
