Morris described the thirteen year-old as "tall and slender, with a very fair skin, and pale golden hair that hung to her shoulders; she was a serious child – devoted to her dancing – she seldom smiled, and had large, thoughtful eyes, but her full curling lips held a promise of sensuality not yet awakened.
"[2] Dillon was trained in Morris's dance technique, which focused on natural, expressionistic movement with bare feet and loose clothing, in contrast to classical ballet.
