Harper Dupree has pinned all her hopes on a future in fashion design. But when it comes crashing down around her, she returns home to Fairhope, Alabama, and to Millie, the woman who first taught her how to sew. As Harper rethinks her own future, long-hidden secrets about Millie's past are brought to light.

In 1946, Millie Middleton - the daughter of an Italian man and a Black woman - boarded a train and left Charleston to keep half of her heritage hidden. She carried with her two heirloom buttons and the dream of owning a dress store. She never expected to meet a charming train jumper who changed her life forever . . . and led her yet again to a heartbreaking choice about which heritage would define her future.

Now, together, Harper and Millie return to Charleston to find the man who may hold the answers they seek . . . and a chance at the dress shop they've both dreamed of. But it's not until all appears lost that they see the unexpected ways to mend what frayed between the seams.
