With her elongated limbs and polished port de bras, Clark is a remarkably self-possessed dancer who uses her 5′ 10 1/2″ frame to fully inhabit every choreographic moment and musical note. She debuted in a slew of roles in 2023, including the Tall Girl in George Balanchine’s “Rubies” and the lead woman in Haieff Divertimento, which hadn’t been performed by NYCB since 1994.
