Harry Styles captivates audiences worldwide with his talent, charisma and sartorial wit. From his early days as a member of the boyband One Direction to his wildly successful solo career, Styles marries mass appeal with a celebration of fluidity; blurring the lines of fashion, musical genres and gender norms. Once dismissed as a flash-in-the-pan teen trend, Styles has proven himself as a once-in-a-generation talent. Today, Harry Styles is less of a pop star and more of a lifestyle.

When her twenty-year marriage ended, Keris Fox fell into the One Direction fandom and her whole life changed.
