Metropolitan Opera House Dress Code - Page 3

Relaxed. FFS, I went there on the 31st of December for an 8pm show. People were dressed in odd jackets, some with jeans. Probably 40% of the men were in suits, out of which 95% wore ill-fitting ones and had ugly, badly tied neckties. Wear a suit and you will stand out.

...in a good way.

Read this too late, decided on an elegant dark wrap dress, it worked. And yes, it was rather warm.
