Learning a variation for the first time is definitely one of the most rewarding parts of ballet. And when American Ballet Theatre principal Isabella Boylston teaches you that variation as part of a master class series hosted by dancewear brand Cloud & Victory, the whole process gets even more exciting. Dreamt up by Cloud & Victory founder Min, the day-long workshop at Joffrey Ballet School in New York City consisted of a technique class taught by fellow ABT principal Gillian Murphy, as well as variations from both Murphy and Boylston. After Murphy taught Black Swan, Boylston gave the dancers another classic with Act I of Giselle. If you weren't lucky enough to be among the dozens of aspiring ballerinas gathered at the master class, check out some of Boylston's tips for learning Giselle at home.
