Neary then recommended Sylve join Dutch National Ballet, which had more Balanchine repertoire.
She was promoted to principal dancer and was offered a lifetime contract at age 20, and danced roles including Aurora in The Sleeping Beauty, as well as works by Balanchine and Frederick Ashton.
In 2003, the New York City Ballet invited Sylve to join the company, and she accepted the position several months lateer.
