Dorothée Gilbert doesn't subscribe to a single sartorial look. "I love to wear a beautiful dress or something very sophisticated for a night out or a party after a show," the Paris Opéra Ballet étoile explains during a tour to New York City. "But for a casual day, I have more of a boyish style, like jeans with a beautiful jacket." Gilbert likes to pair online finds with pieces she collects while traveling or shopping at Parisian vintage stores.

She even finds inspiration from designers that she works with through POB, like Balmain's Olivier Rousteing, who created costumes this past spring for Sébastien Bertaud's new work, Renaissance. "We wore these beautiful jackets with diamonds and pearls for the ballet," Gilbert says. "But I also love Olivier's everyday designs."

Gilbert's twist on classic style translates to her studio look as well, where she adds fun warm-ups to her traditional rehearsal wear. "I prefer leotards—or tunics, as we call them in French—because they're easier for partnering," she says. Another staple? Her black knit pants with a multicolored print down the right leg. "I always wear them before a performance, especially on tour."
