I just won a concerto competition and am now having a problem deciding what to wear for the upcoming concert. I don't perform regularly, but when I do, it's usually in informal recitals so appropriate attire there is a no brainer. This will be a somewhat more formal occasion. I know the orchestra will be wearing black (jackets for men). I don't own a black suit, but I do have a black tuxedo. Even though the tux is rather understated, I'm wondering if that's too formal for a Sunday afternoon concert, and if I need to go out and purchase a black suit (something I haven't needed in years and don't expect to any other time). Does it really matter? Bow tie? Any thoughts?
