Paris, 1958: Rose, a seamstress at a fashionable atelier, has been entrusted with sewing a Grace Kelly—look-alike gown for a wealthy bride-to-be. But when, against better judgment, she finds herself falling in love with the bride’s handsome brother, Rose must make an impossible choice, one that could put all she’s worked for at risk: love, security and of course, the dress.Sixty years later, tech CEO Rachel, who goes by the childhood nickname “Rocky,” has inherited the dress for her upcoming wedding in New York City. But there’s just one problem: Rocky doesn’t want to wear it. A family heirloom dating back to the 1950s, the dress just isn’t . Rocky knows this admission will break her mother Joan’s heart. But what she doesn’t know is Joan insists on the dress—or the heartbreaking secret that changed her mother’s life decades before, as she herself prepared to wear it.As the lives of these three women come together in surprising ways, the revelation of the dress’s history collides with long-buried family heartaches. And in the lead-up to Rocky’s wedding, they’ll have to confront the past before they can embrace the beautiful possibilities of the future.
