Ballet season is upon us: The New York City Ballet opened its spring season last week, and last night, the dancers of NYCB faced off against the American Ballet Theater in a nail-biter of a ping-pong match. But it’s not just about pointe shoes and ultra-flexibility — ballet also offers a few spring beauty inspirations like exaggerated eyeliner and bold brows. Most of all, on-stage beauty is defined by the ballet bun, a sleek, tight knot at the nape of the neck. As the weather changes, a bun is both utilitarian and cute, keeping hair up and away from the face and neck. Here, find a few of our favorite buns — inspired by ballet and beyond — that take the hair style to the next level. Pirouettes not included.
