Fan Casting Belly Conklin in The Summer I Turned Pretty

Belly Conklin (Isabel Conklin) is the heart of The Summer I Turned Pretty. Thoughtful, sensitive, and quietly strong, Belly is a girl caught between childhood and adulthood, discovering who she is during the defining summers of her life. She’s been coming to Cousins Beach every year since she was little, but now—on the cusp of sixteen—everything is starting to change. Belly is deeply loyal to her family and friends but struggles with insecurities and the growing pains of adolescence. Her character is marked by emotional depth, curiosity, and a longing to be seen not just as the little sister or best friend, but as her own person. As she navigates first love, heartbreak, and self-discovery, Belly’s inner world reveals the universal messiness of growing up—complicated, raw, and beautiful.
