Few things excite us more than when two of our greatest passions collide, so this season's fashion-filled New York City Ballet Gala is giving us many reasons to leap from our seats. Fashion heavyweights including Carolina Herrera, Sarah Burton for Alexander McQueen, Thom Browne and Mary Katrantzou collaborated with New York City Ballet's Costume Shop on sartorial sensations for four ballets, and we got a behind-the-scenes look. As one might expect, the designers stayed true to their respective aesthetics when approaching ballet costume design.
