I will be attending a gala honoring a former boss from many years ago. Takes place on a Monday night in mid-May; 6:30 cocktails, 7:30 performances (by Sir James and Lady Jeanne Galway, and Ailyn Pérez) and dinner. "Festive attire."
I haven't been to anything like this since 1982. And I no longer own the dress I wore to that. I have a sparkly black "cocktail suit" and black patent flats, which I wore to an evening wedding a couple of years ago. Will those be "festive" enough?
Also: is it better to break out the diamonds, or will garnets do?
