Wednesday, March 5th

Beef up that botox and skip dinner, ladies, it’s almost time for that singular New York gloriousness known as gala season! Up first, the New York City Opera, which stages its spring gala in trendy high-low fashion, featuring both Shakespeare—Henry Purcell’s King Arthur—and mass-market king Isaac Mizrahi, the show’s costume designer. (Um, happy dagger, please!)

[New York City Opera Spring Gala, New York State Theater, 6 p.m., 212-870-5622]
