In films, books, plays and works of art, one item can become piled high with layers of meaning; Desdemona’s handkerchief, Matisse’s apple, Dorothy’s ruby slippers. In Lucy Hilmer’s photography series Birthday Suits, one pair of white pants comes to stand for more than itself. Baring almost all, Lucy stands before the camera; sometimes defiant, sometimes distressed, most often smiling. There’s something deeply personal and poetic about these pictures which made me want to learn more about the woman – and the pants – at the centre of them. So over to Lucy, who answers a few of my questions.
