I have the opportunity to attend my first performance at the NY Met Opera and was wondering, not surprisingly, what a well-dressed 20-something would wear to the Opera. Â I DON'T have a black suit in my closet right now, so my choices are limited to the following: 1) Charcoal SB sportcoat 2) Black cashmere SB SC 3) SB 3B pinstripe navy suit 4) Sb 2B navy/gray windowpane suit I'm leaning towards the black SC with a pair of windowpane trousers, check shirt and tie. Â The blue suits are decidely more formal, but lacks the flair that I'm seeking... Any recommendations on shirt colors? Â How conservative should I be? Â Are pinks and lavenders not apropos?
