Really, you can wear what you damn well please at the Met. Me, I almost always wear a suit (we go 10 or 12 times a year), but I'd probably wear a suit to the beach if I ever went to the beach. People wear jeans and sweaters to the Met, at all ticket prices. It really doesn't matter. It's about the performance, not about the audience. The only time I ever felt I needed to wear black tie to the opera was at Monte Carlo, where probably 80 per cent of the men were thus attired. I'd asked beforehand, and my contacts said it was unnecessary - but I sensed from their tone that what they really meant was, "Please, please, please don't come in anything BUT black tie." When we met before the first of the shows we were to see, they actually told us how relieved they were that I was all riveted into a stiff shirt. It was, of course, fun to dress up - the Monte Carlo opera house is in the casino building and is extraordinarily fancy.
