Symphony season is in full swing, and questions about what to wear often show up. Nowadays for most performances, people visiting will be in a wide range of different attire, getting more casual as you move further west from New York and Chicago.

Here’s the general rule of thumb: dinner jackets are now typically only worn during opening nights and gala events. For all other nights, a dark suit or sportcoat with odd trousers are ideal – pair with a muted tie, pocket square, and captoe shoes and you’re all set.
