In addition to her jewelry, Lively also wore her personal pair of $2,990 Saint Laurent boots and borrowed clothing from her friend Gigi Hadid. By contributing her own wardrobe, Lively not only saved on the film's budget but also ensured a personal touch to her character's style. The film, based on Colleen Hoover's novel, features an ensemble cast including Justin Baldoni and Jenny Slate, and is set to release soon. Critics have noted Lively's influence on the film's visual appeal and character development, underscoring her dedication to the role.
