Misty Copeland has far-transcended the rarefied world of ballet, appearing as a guest judge on “So You Think You Can Dance,” touring with Prince and serving as the face of Estée Lauder’s Modern Muse fragrance — not to mention attracting more than 1.5 million Instagram followers.

I think the fact that me, a black woman, is what has kind of introduced a lot of people to the ballet world is huge. It’s definitely forced a lot of ballet companies to address the issue of the lack of diversity. You know — and I constantly say this — even if it’s not something that they’ve ever wanted to do, the world is looking in now. More so than ever before. The ballet world is so secluded and lives in this bubble, and it’s easy to get away with a lot. So with the attention I’ve brought to ballet, I think they’re
