DH and I are invited to a wedding in two months. It starts at 5pm. The invite says "black tie preferred". I was hoping this would be a cheaper wedding for us since it's local (aka no hotel/flight costs) and most other weddings tend to be out of town for us. Is there a way to get around DH renting a tux? I'm not really concerned about other's judging us since we won't know anyone else at this wedding (yeah, should be fun, LOL...). Is it bad if he doesn't wear a tux (which we'd have to rent and isn't cheap in NYC)? If he wears a dark suit instead, what should I be wearing?
